OpenPAM Ximenia 2023-06-27
|
|
|
|
- BUGFIX: Fix race condition in openpam_ttyconv(3) when used with
|
|
expect scripts.
|
|
|
|
- BUGFIX: In openpam_set_option(3), when removing an option, properly
|
|
decrement the option count.
|
|
|
|
- BUGFIX: In openpam_subst(3), avoid incrementing past the end of the
|
|
template.
|
|
============================================================================
|
|
OpenPAM Tabebuia 2019-02-24
|
|
|
|
- BUGFIX: Fix off-by-one bug in pam_getenv(3) which was introduced in
|
|
OpenPAM Radula.
|
|
|
|
- ENHANCE: Add unit tests for pam_{get,put,set}env(3).
|
|
============================================================================
|
|
OpenPAM Resedacea 2017-04-30
|
|
|
|
- BUGFIX: Reinstore the NULL check in pam_end(3) which was removed in
|
|
OpenPAM Radula, as it breaks common error-handling constructs.
|
|
|
|
- BUGFIX: Return PAM_SYMBOL_ERR instead of PAM_SYSTEM_ERR from the
|
|
dispatcher when the required service function could not be found.
|
|
|
|
- ENHANCE: Introduce the PAM_BAD_HANDLE error code for when pamh is
|
|
NULL in API functions that have a NULL check.
|
|
|
|
- ENHANCE: Introduce the PAM_BAD_ITEM, PAM_BAD_FEATURE and
|
|
PAM_BAD_CONSTANT error codes for situations where we previously
|
|
incorrectly used PAM_SYMBOL_ERR to denote that an invalid constant
|
|
had been passed to an API function.
|
|
|
|
- ENHANCE: Improve the RETURN VALUES section in API man pages,
|
|
especially for functions that cannot fail, which were incorrectly
|
|
documented as returning -1 on failure.
|
|
============================================================================
|
|
OpenPAM Radula 2017-02-19
|
|
|
|
- BUGFIX: Fix an inverted test which prevented pam_get_authtok(3) and
|
|
pam_get_user(3) from using application-provided custom prompts.
|
|
|
|
- BUGFIX: Plug a memory leak in pam_set_item(3).
|
|
|
|
- BUGFIX: Plug a potential memory leak in openpam_readlinev(3).
|
|
|
|
- BUGFIX: In openpam_readword(3), support line continuations within
|
|
whitespace.
|
|
|
|
- ENHANCE: Add a feature flag to control fallback to "other" policy.
|
|
|
|
- ENHANCE: Add a pam_return(8) module which returns an arbitrary
|
|
code specified in the module options.
|
|
|
|
- ENHANCE: More and better unit tests.
|
|
============================================================================
|
|
OpenPAM Ourouparia 2014-09-12
|
|
|
|
- ENHANCE: When executing a chain, require at least one service
|
|
function to succeed. This mitigates fail-open scenarios caused by
|
|
misconfigurations or missing modules.
|
|
|
|
- ENHANCE: Make sure to overwrite buffers which may have contained an
|
|
authentication token when they're no longer needed.
|
|
|
|
- BUGFIX: Under certain circumstances, specifying a non-existent
|
|
module (or misspelling the name of a module) in a policy could
|
|
result in a fail-open scenario. (CVE-2014-3879)
|
|
|
|
- FEATURE: Add a search path for modules. This was implemented in
|
|
Nummularia but inadvertently left out of the release notes.
|
|
|
|
- BUGFIX: The is_upper() predicate only accepted the letter A as an
|
|
upper-case character instead of the entire A-Z range. As a result,
|
|
service and module names containing upper-case letters other than A
|
|
would be rejected.
|
|
============================================================================
|
|
OpenPAM Nummularia 2013-09-07
|
|
|
|
- ENHANCE: Rewrite the dynamic loader to improve readability and
|
|
reliability. Modules can now be listed without the ".so" suffix in
|
|
the policy file; OpenPAM will automatically add it, just like it
|
|
will automatically add the version number if required.
|
|
|
|
- ENHANCE: Allow openpam_straddch(3) to be called without a character
|
|
so it can be used to preallocate a string.
|
|
|
|
- ENHANCE: Improve portability by adding simple asprintf(3) and
|
|
vasprintf(3) implementations for platforms that don't have them.
|
|
|
|
- ENHANCE: Move the libpam sources into a separate subdirectory.
|
|
|
|
- ENHANCE: Substantial documentation improvements.
|
|
|
|
- BUGFIX: When openpam_readword(3) encountered an opening quote, it
|
|
would set the first byte in the buffer to '\0', discarding all
|
|
existing text and, unless the buffer was empty to begin with, all
|
|
subsequent text as well. This went unnoticed because none of the
|
|
unit tests for quoted strings had any text preceding the opening
|
|
quote.
|
|
|
|
- BUGFIX: make --with-modules-dir work the way it was meant to work
|
|
(but never did).
|
|
============================================================================
|
|
OpenPAM Micrampelis 2012-05-26
|
|
|
|
- FEATURE: Add an openpam_readword(3) function which reads the next
|
|
word from an input stream, applying shell quoting and escaping
|
|
rules. Add numerous unit tests for openpam_readword(3).
|
|
|
|
- FEATURE: Add an openpam_readlinev(3) function which uses the
|
|
openpam_readword(3) function to read words from an input stream one
|
|
at a time until it reaches an unquoted, unescaped newline, and
|
|
returns an array of those words. Add several unit tests for
|
|
openpam_readlinev(3).
|
|
|
|
- FEATURE: Add a PAM_HOST item which pam_start(3) initializes to the
|
|
machine's hostname. This was implemented in Lycopsida but
|
|
inadvertantly left out of the release notes.
|
|
|
|
- FEATURE: In pam_get_authtok(3), if neither the application nor the
|
|
module have specified a prompt and PAM_HOST and PAM_RHOST are both
|
|
defined but not equal, use a different default prompt that includes
|
|
PAM_USER and PAM_HOST.
|
|
|
|
- ENHANCE: Rewrite the policy parser to used openpam_readlinev(),
|
|
which greatly simplifies the code.
|
|
|
|
- ENHANCE: The previous implementation of the policy parser relied on
|
|
the openpam_readline(3) function, which (by design) munges
|
|
whitespace and understands neither quotes nor backslash escapes.
|
|
As a result of the aforementioned rewrite, whitespace, quotes and
|
|
backslash escapes in policy files are now handled in a consistent
|
|
and predictable manner.
|
|
|
|
- ENHANCE: On platforms that have it, use fdlopen(3) to load modules.
|
|
This closes the race between the ownership / permission check and
|
|
the dlopen(3) call.
|
|
|
|
- ENHANCE: Reduce the amount of pointless error messages generated
|
|
while searching for a module.
|
|
|
|
- ENHANCE: Numerous documentation improvements, both in content and
|
|
formatting.
|
|
|
|
- BUGFIX: A patch incorporated in Lycopsida inadvertantly changed
|
|
OpenPAM's behavior when several policies exist for the same
|
|
service, from ignoring all but the first to concatenating them all.
|
|
Revert to the original behavior.
|
|
|
|
- BUGFIX: Plug a memory leak in the policy parser.
|
|
============================================================================
|
|
OpenPAM Lycopsida 2011-12-18
|
|
|
|
- ENHANCE: removed static build autodetection, which didn't work
|
|
anyway. Use an explicit, user-specified preprocessor variable
|
|
instead.
|
|
|
|
- ENHANCE: cleaned up the documentation a bit.
|
|
|
|
- ENHANCE: added openpam_subst(3), allowing certain PAM items to be
|
|
embedded in strings such as prompts. Apply it to the prompts used
|
|
by pam_get_user(3) and pam_get_authtok(3).
|
|
|
|
- ENHANCE: added support for the user_prompt, authtok_prompt and
|
|
oldauthtok_prompt module options, which override the prompts passed
|
|
by the module to pam_set_user(3) and pam_get_authtok(3).
|
|
|
|
- ENHANCE: rewrote the policy parser to support quoted option values.
|
|
|
|
- ENHANCE: added pamtest(1), a tool for testing modules and policies.
|
|
|
|
- ENHANCE: added code to check the ownership and permissions of a
|
|
module before loading it.
|
|
|
|
- ENHANCE: added / improved input validation in many cases, including
|
|
the policy file and some function arguments. (CVE-2011-4122)
|
|
============================================================================
|
|
OpenPAM Hydrangea 2007-12-21
|
|
|
|
- ENHANCE: when compiling with GCC, mark up API functions with GCC
|
|
attributes where appropriate.
|
|
|
|
- BUGFIX: fixed numerous warnings uncovered by GCC 4.
|
|
|
|
- ENHANCE: building the documentation is now optional.
|
|
|
|
- ENHANCE: corrected a number of mistakes and style issues in the
|
|
build system.
|
|
|
|
- ENHANCE: API function arguments are now const where appropriate, to
|
|
match corresponding changes in the Solaris PAM and Linux-PAM APIs.
|
|
|
|
- ENHANCE: corrected a number of C namespace violations.
|
|
|
|
- ENHANCE: the module cache has been removed, allowing long-lived
|
|
applications to pick up module changes. This also allows multiple
|
|
threads to use PAM simultaneously (as long as they use separate PAM
|
|
contexts), since the module cache was the only part of OpenPAM that
|
|
was not thread-safe.
|
|
============================================================================
|
|
OpenPAM Figwort 2005-06-16
|
|
|
|
- BUGFIX: Correct several small signedness and initialization bugs
|
|
discovered during review by the NetBSD team.
|
|
|
|
- BUGFIX: Modify gendoc.pl to sort cross-references in dictionary
|
|
order within each section.
|
|
|
|
- ENHANCE: if a policy specifies a relative module path, prepend the
|
|
module directory so we never call dlopen(3) with a relative path.
|
|
|
|
- ENHANCE: add a pam.conf(5) manual page.
|
|
============================================================================
|
|
OpenPAM Feterita 2005-02-01
|
|
|
|

|
|
and other issues in the manual pages, with kind assistance from
|
|
Ruslan Ermilov <ru@freebsd.org>.
|
|
|
|
- BUGFIX: Avoid multiple evaluation of macro arguments in ENTERX()
|
|
and RETURNX() macros.
|
|
|
|
- BUGFIX: Remove an unnecessary and non-portable pointer cast in
|
|
pam_get_data(3).
|
|
|
|
- BUGFIX: Fix identical typos in PAM_ACCT_EXPIRED case in
|
|
pam_strerror(3) and gendoc.pl.
|
|
|
|

|
|
|
|
- ENHANCE: Add openpam_free_envlist(3).
|
|
============================================================================
|
|
OpenPAM Eelgrass 2004-02-10
|
|
|
|
- BUGFIX: Correct array handling bugs in conversation code.
|
|
|
|
- BUGFIX: In openpam_ttyconv(3), don't strip trailing linear
|
|
whitespace from the user's response.
|
|
|
|
- BUGFIX: Many constness issues addressed.
|
|
============================================================================
|
|

- ENHANCE: Constify the msg field in struct pam_message.
|
|
|
|
- BUGFIX: Remove left-over debugging output
|
|
|
|
- BUGFIX: Avoid side effects in arguments to the FREE() macro
|
|
|
|
- ENHANCE: Make openpam_ttyconv(3) use read(2) rather than fgets(3).
|
|
|
|
- BUGFIX: Staticize some variables which shouldn't be global.
|
|
|
|
- BUGFIX: Correcly anticipate a NULL user in pam_get_user(3).
|
|
|
|
- ENHANCE: Various minor documentation improvements.
|
|
|
|
Thanks to Dmitry V. Levin <ldv@altlinux.org> for considerable
|
|
assistance with this release.
|
|
============================================================================
|
|
OpenPAM Digitalis 2003-06-01
|
|
|
|
- ENHANCE: Completely rewrite the configuration parser and add
|
|
support for the "include" control flag.
|
|
|
|
- ENHANCE: Improve portability to NetBSD, OpenBSD and Linux.
|
|
|
|
- ENHANCE: Lots of additional paranoia.
|
|
|
|
- BUGFIX: The sample su(1) application dropped privileges before
|
|
forking instead of after.
|
|
|
|
- ENHANCE: Document openpam_log(3).
|
|
|
|
- ENHANCE: Other minor documentation fixes.
|
|
|
|
Thanks to Dmitry V. Levin <ldv@altlinux.org> for considerable
|
|
assistance with this release.

============================================================================
|
|
OpenPAM Dianthus 2003-05-02
|
|
|
|
- BUGFIX: Initialize some potentially uninitialized variables.
|
|
|
|
- BUGFIX: Silence some warnings emitted by gcc -std=iso9899:1999.
|
|
|
|
- BUGFIX: In pam_getenv(), return a pointer to the stored variable
|
|
instead of a freshly allocated copy.
|
|
|
|
- ENHANCE: Detect recursion in openpam_borrow_cred()
|
|
|
|
- ENHANCE: Make borrowing one's own credentials a no-op.
|
|
|
|
- ENHANCE: Further improve debugging support.
|
|
|
|
- ENHANCE: Clean up some variable names.
|
|
============================================================================
|
|
OpenPAM Daffodil 2003-01-06
|
|
|
|
- ENHANCE: Document dependency on <sys/types.h> (for size_t)
|

|
|
============================================================================
|
|

|
|
functions.
|
|
|

than stderr.
|
|
============================================================================
|
|
OpenPAM Citronella 2002-06-30
|
|
|
|
- ENHANCE: Add the "binding" control flag (from Solaris 9).
|
|
|
|
- ENHANCE: Define struct pam_repository and PAM_REPOSITORY (from
|
|
Solaris 9).
|
|
|
|
- ENHANCE: Flesh out the pam(3) man page.
|
|
|
|
- ENHANCE: Add an openpam(3) page with cross-references to all the
|

|
|
============================================================================
|
|
OpenPAM Cinnamon 2002-05-02

|
|
|
|
- BUGFIX: Duplicate expansion of openpam_log() macro arguments.
|
|
|
|
- ENHANCE: Restructure the policy-loading code and align our use of
|
|
the "other" policy with Solaris and Linux-PAM.
|
|
|
|
- ENHANCE: Log dlopen() and dlsym() failures.
|
|
|
|
- ENHANCE: In openpam_ttyconv(), emit a newline after error and info
|
|
messages unless the message contains one already.
|
|
|
|
- BUGFIX: In pam_vprompt(), initialize the response pointer to NULL
|
|
so we can detect whether the conversation function touched it.
|
|
============================================================================
|
|
OpenPAM Cineraria 2002-04-14
|
|
|
|
- BUGFIX: Fix confusion between token and prompt in
|
|
pam_get_authtok(3).
|
|
|
|
- ENHANCE: Improved documentation.
|
|
|
|
- ENHANCE: Adopt the same preprocessor tricks that were used in
|
|
FreeBSD's version of Linux-PAM to simplify static linking without
|
|
requiring dummy primitives.
|
|
|
|
- ENHANCE: Move the policy-loading code out of pam_start.c.
|
|
|
|
- BUGFIX: Fix typo in one of the versions of the openpam_log macro.
|
|
|
|
- ENHANCE: Add versioning macros.
|
|
============================================================================
|
|
OpenPAM Cinchona 2002-04-08
|
|
|
|
- ENHANCE: Improved documentation for several API functions.
|
|
|
|
- BUGFIX: Fix bug in pam_set_data() that would result in corruption
|
|
of the module data list.
|
|
|
|
- BUGFIX: Allocate the correct amount of memory for the environment
|
|
list in pam_putenv().
|
|
|
|
- ENHANCE: Change pam_get_authtok()'s prototype so the caller can
|
|
specify what token it wants. Also introduce PAM_OLDAUTHTOK_PROMPT.
|
|
|
|
- BUGFIX: Plug memory leak in pam_get_user() / pam_get_authtok(), and
|
|
reduce differences between these very similar functions.
|
|
|
|
- ENHANCE: Check flags carefully in pam_authenticate() and
|
|
pam_chauthtok().
|
|
|
|
- BUGFIX: Fix bugs in portability code; libpam now builds on NetBSD.
|
|
|
|
- ENHANCE: In pam_get_authtok(), if PAM_OLDAUTHTOK is set, we're
|
|
asked for PAM_AUTHTOK, and we have to prompt the user, prompt her
|
|
twice and compare the responses.
|
|
|
|
- ENHANCE: Add openpam_{borrow,restore}_cred(), for temporarily
|
|
switching to user credentials.
|
|
|
|
- ENHANCE: Add openpam_free_data(), a generic cleanup function for
|
|
pam_set_data() consumers.
|
|
============================================================================
|
|
OpenPAM Centaury 2002-03-14
|
|
|
|
- BUGFIX: Add missing #include <string.h> to openpam_log.c.
|
|
|
|
- BUGFIX: s/PAM_REINITIALISE_CRED/PAM_REINITIALIZE_CRED/. XSSO uses
|
|
the former, but Solaris and Linux-PAM use the latter.
|
|
|
|
- BUGFIX: The dynamic loader and the module cache contained a number
|
|
of bugs which would cause a segmentation fault if pam_start(3) was
|
|
called again after pam_end(3), as happens in login(1), xdm(1) etc.
|
|
after a failed login.
|
|
|
|
- BUGFIX: Refer to a module by the name used in the policy file, even
|
|
if the module that was actually loaded was versioned.
|
|
|
|
- ENHANCE: Suppress debugging logs, unless compiled with -DDEBUG.
|
|
============================================================================
|
|
OpenPAM Celandine 2002-03-05
|
|
|
|
- BUGFIX: PAM_TRY_AGAIN is a valid return value for pam_chauthtok().
|
|
|
|
- BUGFIX: Run passwd chain twice, first with the PAM_PRELIM_CHECK
|
|
flag set, then with the PAM_UPDATE_AUTHTOK flag set.
|
|
|
|
- BUGFIX: Failure of a "sufficient" module should not terminate the
|
|
passwd chain if the PAM_PRELIM_CHECK flag is set.
|
|
|
|
- BUGFIX: Clear PAM_AUTHTOK after running the service modules.
|
|
|
|
- ENHANCE: Prevent applications from specifying the PAM_PRELIM_CHECK
|
|
or PAM_UPDATE_AUTHTOK flags themselves.
|
|
|
|
- BUGFIX: openpam_set_option() did not support changing the value of
|
|
an existing option.
|
|
|
|
- ENHANCE: Add support for module versioning. OpenPAM will prefer a
|
|
module with the same version number as the library itself to one
|
|
with no version number at all.
|
|
============================================================================
|
|
OpenPAM Cantaloupe 2002-02-22
|
|
|
|
- BUGFIX: The proper use of PAM_SYMBOL_ERR is to indicate an invalid
|
|
argument to pam_[gs]et_item(3), not to indicate dlsym(3) failures.
|
|
|
|
- ENHANCE: Add in-line documentation in most source files, and a Perl
|
|
script that generates mdoc code from that.
|
|
|
|
- BUGFIX: The environment list was not properly NULL-terminated.
|
|
|
|
- ENHANCE: Allow the PAM_AUTHTOK_PROMPT item to override the prompt
|
|
specified by the module.
|
|
|
|
- BUGFIX: PAM_NUM_ITEMS was set too low. It has been moved to
|
|
pam_constants.h to avoid it going stale again.
|
|
|
|
- ENHANCE: Move all code related to static modules into a separate
|
|
file.
|
|
|
|
- ENHANCE: openpam_ttyconv() now masks most signals while prompting the
|
|
user, and supports setting a timeout (which defaults to off).
|
|
|
|
- BUGFIX: Some manual pages referenced XSSO even though they
|
|
documented OpenPAM-specific functions.
|
|
|
|
- ENHANCE: Added openpam_get_option() and openpam_set_option().
|
|
|
|
- ENHANCE: openpam_get_authtok() now respects the echo_pass,
|
|
try_first_pass, and use_first_pass options.
|
|
============================================================================
|
|
OpenPAM Caliopsis 2002-02-13
|
|
|
|
Fixed a number of bugs in the previous release, including:
|
|
- a number of bugs in and related to pam_[gs]et_item(3)
|
|
- off-by-one bug in pam_start.c would trim last character off certain
|
|
configuration lines
|
|
- incorrect ordering of an array in openpam_load.c would cause service
|
|
module functions to get mixed up
|
|
- missing 'continue' in openpam_dispatch.c caused successes to be
|
|
counted as failures
|
|
============================================================================
