<para>(30 Jan 2004, updated 28 Feb 2004) A bug in &man.mksnap.ffs.8; causes the creation of a
filesystem snapshot to reset the flags on the filesystem to
their default values. The possible consequences depend on local
usage, but can include disabling extended access control lists
or enabling the use of setuid executables stored on an untrusted
filesystem. This bug also affects the &man.dump.8;
<option>-L</option> option, which uses &man.mksnap.ffs.8;. Note
that &man.mksnap.ffs.8; is normally only available to the
superuser and members of the <groupname>operator</groupname>
group. This bug has been fixed on the &os; &release.prev;
security fix branch and in &os; &release.bugfix;. For more information, see security advisory <ulink
url="ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-04:01.mksnap_ffs.asc">FreeBSD-SA-04:01</ulink>.</para>
<para>(8 Feb 2004, updated 28 Feb 2004) A bug with the System V Shared Memory interface
(specifically the &man.shmat.2; system call)
can cause a shared memory segment to reference
unallocated kernel memory. In turn, this can permit a local
attacker to gain unauthorized access to parts of kernel memory,
possibly resulting in disclosure of sensitive information,
bypass of access control mechanisms, or privilege escalation.
This bug has been fixed on the &os; &release.prev;
security fix branch and in &os; &release.bugfix;.
More details, including bugfix and workaround information,
can be found in security advisory <ulink
url="ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-04:02.shmat.asc">FreeBSD-SA-04:02</ulink>.</para>
<para>(28 Feb 2004) It is possible, under some circumstances, for
a processor with superuser privileges inside a &man.jail.8;
environment to change its root directory to a different jail,
giving it read and write access to the files and directories
within. This vulnerability has been closed on the &os;
&release.prev; security fix branch and in &os;
&release.bugfix;. Information on the bug fix can be found in
security advisory <ulink
url="ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-04:03.jail.asc">FreeBSD-SA-04:03</ulink>.</para>
<para>(4 Mar 2004) It is possible for a remote attacker to conduct
a low-bandwidth denial-of-service attack against a machine
providing TCP-based services, filling up the target's memory
buffers and potentially leading to a system crash. This
vulnerability has been addressed on the &os; &release.prev;
security fix branch, but is present in both &os; &release.prev;
and &release.bugfix;. Security advisory <ulink
url="ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-04:04.tcp.asc">FreeBSD-SA-04:04</ulink>
contains more details, as well as information on patching
existing systems.</para>
<para>(17 Mar 2004) By performing a specially crafted SSL/TLS
handshake with an application that uses OpenSSL a null pointer
may be dereferenced. This may in turn cause the application to
crash, resulting in a denial of service attack. For more information
see the Security Advisory <ulink
url="ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-04:05.openssl.asc">FreeBSD-SA-04:05</ulink>
which contains more details and instructions on how to patch existing
systems.</para>
<para>(29 Mar 2004) A local attacker may take advantage of a
programming error in the handling of certain IPv6 socket options
in the &man.setsockopt.2; system call to read portions of kernel
memory without proper authorization. This may result in disclosure
of sensitive data, or potentially cause a panic. See Security
Advisory <ulink
url="ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-04:06.ipv6.asc">FreeBSD-SA-04:06</ulink>
for a more detailed description and instructions on how to patch
existing systems.</para>
<para>(9 May 2004) Two programming errors in
<application>CVS</application> can allow a server to overwrite
arbitrary files on the client, and a client to read arbitrary
files on the server when accessing remote CVS repositories.

<para>(9 Jan 2004) Due to a change in &man.cpp.1; behavior, the
login screen for &man.xdm.1; is in black and white, even on
systems with color displays. As a workaround, update to a newer
version of the
<filename role="package">x11/XFree86-4-clients</filename>
port/package.</para>
<para>(9 Jan 2004) There remain some residual problems with ACPI.
In some cases, systems may behave erratically, or hang at boot
time. As a workaround, disable ACPI, using the <quote>safe
mode</quote> option of the bootloader or using the
<varname>hint.acpi.0.disabled</varname> kernel environment
variable. These problems are being investigated. For problems
that have not already been reported (check the mailing list
archives <emphasis>before</emphasis> posting), sending the
output of &man.dmesg.8; and &man.acpidump.8; to the
&a.current; may help diagnose the problem.</para>
<para>(9 Jan 2004, updated 28 Feb 2004) In some cases, ATA devices may behave
erratically, particularly SATA devices. Reported symptoms
include command timeouts or missing interrupts. These problems
appear to be timing-dependent, making them rather difficult to
isolate. Workarounds include:</para>
<itemizedlist>
<listitem>
<para>Turn off ATA DMA using the <quote>safe mode</quote>
option of the bootloader or the
<varname>hw.ata.ata_dma</varname> sysctl variable.</para>
</listitem>
<listitem>
<para>Use the host's BIOS setup options to put the ATA
controller in its <quote>legacy mode</quote>, if
available.</para>
</listitem>
<listitem>
<para>Disable ACPI, for example using the <quote>safe mode</quote>
option of the bootloader or using the
<varname>hint.acpi.0.disabled</varname> kernel environment
variable.</para>
</listitem>
</itemizedlist>
<para>Some of these problems were addressed in &os;
&release.bugfix; with the import of a newer &man.ata.4; from
&release.current;.</para>
<para>(9 Jan 2004) Installing over NFS when using the install
floppies requires that the <filename>nfsclient.ko</filename>
module be manually loaded from the third floppy disk. This can
be done by following the prompts when &man.sysinstall.8;
launches to load a driver off of the third floppy disk.</para>
<para>(9 Jan 2004) The use of multiple vchans (virtual audio
channels with dynamic mixing in software) in the &man.pcm.4;
driver has been known to cause some instability.</para>
<para>(10 Jan 2004) Although APIC interrupt routing seems to work
correctly on many systems, on some others (such as some laptops)
it can cause various errors, such as &man.ata.4; errors or hangs
when starting or exiting X11. For these situations, it may be
advisable to disable APIC routing, using the <quote>safe
mode</quote> of the bootloader or the
<varname>hint.apic.0.disabled</varname> loader tunable. Note
that disabling APIC is not compatible with SMP systems.</para>
<para>(10 Jan 2004, updated 28 Feb 2004) The NFSv4 client may panic when attempting an
NFSv4 operation against an NFSv3/NFSv2-only server. This
problem has been fixed with revision 1.4 of
<filename>src/sys/rpc/rpcclnt.c</filename> in &os;
&release.current;. It was also fixed in &os;
&release.bugfix;.</para>
<para>(11 Jan 2004, updated 28 Feb 2004) Some problems have been encountered when using
third-party NSS modules, such as <filename>nss_ldap</filename>,
and groups with large membership lists. These have been fixed
with revision 1.2 of <filename>src/include/nss.h</filename> and
revision 1.2 of
<filename>src/lib/libc/net/nss_compat.c</filename> in &os;
&release.current;; this fix was backported to &os;
&release.bugfix;.</para>
<para>(13 Jan 2004) The &os; &release.current; release notes
incorrectly stated that <application>GCC</application> was a
post-release GCC 3.3.3 snapshot. They should have stated that
GCC was a <emphasis>pre-release</emphasis> GCC 3.3.3
snapshot.</para>
<para>(13 Jan 2004, updated 28 Feb 2004) The <filename
role="package">sysutils/kdeadmin3</filename> port/package has a
bug in the <application>KUser</application> component that can
cause deletion of the <username>root</username> user from the
system password file. Users are strongly urged to upgrade to
version 3.1.4_1 of this port/package. The package set included
with &os; &release.bugfix; contains the fixed version of this
package.</para>
<para>(21 Jan 2004, updated 28 Feb 2004) Some bugs in the IPsec implementation imported
from the KAME Project can result in memory objects being freed
before all references to them were removed. Reported symptoms
include erratic behavior or kernel panics after flushing the
Security Policy Database (SPD). Some of these problems have
been fixed in &os; &release.current; in rev. 1.31 of
<filename>src/sys/netinet6/ipsec.c</filename>, rev. 1.136 of
<filename>src/sys/netinet/in_pcb.c</filename>, and revs. 1.63
and 1.64 of <filename>src/sys/netkey/key.c</filename>. These
bugfixes were backported to &os; &release.bugfix;. More
information about these problems has been posted to the
&a.current;, in particular the thread entitled <ulink
url="http://lists.FreeBSD.org/pipermail/freebsd-current/2004-January/thread.html#18084">
<quote>[PATCH] IPSec fixes</quote></ulink>.</para>
<para>(28 Feb 2004) The edition of the Porters Handbook included
with &os; &release.bugfix; contained an incorrect value for
&release.bugfix;'s <varname>__FreeBSD_version</varname>. The
correct value is <literal>502010</literal>.</para>

<![ %release.type.snapshot [
<para>(10 Jan 2004, updated 28 Feb 2004) The TCP implementation in &os; now includes
protection against a certain class of TCP MSS resource
exhaustion attacks, in the form of limits on the size and rate
of TCP segments. The first limit sets the minimum allowed
maximum TCP segment size, and is controlled by the
<varname>net.inet.tcp.minmss</varname> sysctl variable (the
default value is <literal>216</literal> bytes). The second
limit is set by the
<varname>net.inet.tcp.minmssoverload</varname> variable, and
controls the maximum rate of connections whose average segment
size is less than <varname>net.inet.tcp.minmss</varname>.
Connections exceeding this packet rate are reset and dropped.
Because this feature was added late in the &release.prev;
release cycle, connection rate limiting is disabled by default,
but can be enabled manually by assigning a non-zero value to
<varname>net.inet.tcp.minmssoverload</varname>. This feature
was added to &os; &release.prev; too late for inclusion in its
release notes.</para>
