The patches below are available in CVS via the
OPENBSD_2_9 patch branch.
For more detailed information on install patches to OpenBSD, please consult the OpenBSD FAQ.
A security issue exists in the lpd daemon that may allow an attacker
to create arbitrary new files in the root directory. Only machines
with line printer access (ie: listed in either /etc/hosts.lpd or
/etc/hosts.equiv) may be used to mount an attack and the attacker
must have root access on the machine. OpenBSD does not start lpd
in the default installation.
A source code patch exists which remedies the problem.
A security issue exists in the vi.recover script that may allow an attacker
to remove arbitrary zero-length files, regardless of ownership.
A source code patch exists which remedies the problem.
A security hole exists in uuxqt(8)
that may allow an attacker to run arbitrary commands as user uucp and
use this to gain root access.
The UUCP execution daemon, uuxqt(8), has a bug in its command line
parsing routine that may allow arbitrary commands to be run. Because
some UUCP commands are run as root (and daemon) from cron it is possible
to leverage compromise of the UUCP user to gain root.
A source code patch exists which remedies the problem.
A security hole exists in lpd(8)
that may allow an attacker with line printer access to gain root
privileges. A machine must be running lpd to be vulnerable (OpenBSD
does not start lpd by default). Only machines with line printer
access (ie: listed in either /etc/hosts.lpd or /etc/hosts.equiv)
may be used to mount an attack.
A source code patch exists which remedies the problem.
A security hole exists in sendmail(8)
that may allow an attacker on the local host to gain root privileges by
specifying out-of-bounds debug parameters.
A source code patch exists which remedies the problem.
A kernel buffer overflow exists in the NFS mount code. An attacker may
use this overflow to execute arbitrary code in kernel mode. However,
only users with mount(2)
privileges can initiate this attack. In default installs, only super-user has
mount privileges. The kern.usermount sysctl(3) controls whether other users have mount privileges.
A source code patch exists which remedies the problem.
The
packages(7)
subsystem incorrectly accepts some package dependencies as okay (see
packages-specs(7)
for details).
A source code patch exists which remedies the problem,
by forcing /usr/sbin/pkg to be more careful in checking
version numbers.
twe(4)
mishandles the DMA mapping resulting in a kernel panic on unaligned data
transfers, induced by programs such as
disklabel(8)
and
dump(8).
A source code patch exists which remedies the problem.
This is the second version of the patch.
A race condition exists in the kernel execve(2) implementation that opens a small window of vulnerability for a non-privileged user to ptrace(2) attach to a suid/sgid process.
A source code patch exists which remedies the problem.
sshd(8)
allows users to delete arbitrary files named "cookies" if X11
forwarding is enabled. X11 forwarding is disabled by default.
A source code patch exists which remedies the problem.
pwd_mkdb(8)
corrupts /etc/pwd.db when modifying an existing user.
A source code patch exists which remedies the problem.
isakmpd(8)
will fail to use a certificate with an identity string that is
exactly N * 8 bytes long.
A source code patch exists which remedies the problem.
The 2.9 CD cover states that XFree86 3.3.6-current is included. This is only half-true.
In fact, the XFree86 included for all architectures is 4.0.3. On the i386, the
3.3.6 Xservers have also been included, because 4.0.3 still has weak support for
some devices which 3.3.6 supported better.
Programs using the fts(3)
routines (such as rm, find, and most programs that take a -R
flag) can be tricked into changing into the wrong directory if the
parent dir is changed out from underneath it. This is similar to
the old fts bug but happens when popping out of directories, as
opposed to descending into them.
A source code patch exists which remedies the problem.
This is the second version of the patch.
The signal handlers in sendmail(8) contain code that is unsafe in the
context of a signal handler. This leads to potentially serious
race conditions. At the moment this is a theoretical attack only
and can only be exploited on the local host (if at all).
A source code patch exists which remedies the problem by updating sendmail to version 8.11.4.
