Patches for the OpenBSD base system are distributed as unified diffs.
Each patch contains usage instructions.
All the following patches are also available in one
tar.gz file
for convenience.
Patches for supported releases are also incorporated into the
-stable branch.
001: SECURITY FIX: April 27, 2007All architectures
Incorrect mbuf handling for ICMP6 packets.
Using
pf(4)
to avoid the problem packets is an effective workaround until the patch
can be installed.
Use "block in inet6" in /etc/pf.conf
A source code patch exists which remedies this problem.
004: SECURITY FIX: April 27, 2007All architectures
Multiple vulnerabilities have been discovered in X.Org.
XC-MISC extension ProcXCMiscGetXIDList memory corruption vulnerability,
BDFFont parsing integer overflow vulnerability,
fonts.dir file parsing integer overflow vulnerability,
multiple integer overflows in the XGetPixel() and XInitImage functions
in ImUtil.c.
CVE-2007-1003,
CVE-2007-1351,
CVE-2007-1352,
CVE-2007-1667.
A source code patch exists which remedies this problem.
005: SECURITY FIX: April 27, 2007All architectures
IPv6 type 0 route headers can be used to mount a DoS attack against
hosts and networks. This is a design flaw in IPv6 and not a bug in
OpenBSD.
A source code patch exists which remedies this problem.
010: SECURITY FIX: October 8, 2007All architectures
Malicious DHCP clients could cause dhcpd(8) to corrupt its stack
A DHCP client that claimed to require a maximum message size less than
the minimum IP MTU could cause dhcpd(8) to overwrite stack memory.
A source code patch exists which remedies this problem.
015: SECURITY FIX: March 30, 2008All architectures
sshd(8) would execute ~/.ssh/rc even when a sshd_config(5) ForceCommand
directive was in effect, allowing users with write access to this file to
execute arbitrary commands. This behaviour was documented, but was an unsafe
default and an extra hassle for administrators.
A source code patch exists which remedies this problem.
016: SECURITY FIX: April 3, 2008All architectures
Avoid possible hijacking of X11-forwarded connections with sshd(8)
by refusing to listen on a port unless all address families bind
successfully.
A source code patch exists which remedies this problem.
