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
<a href="https://ftp.openbsd.org/pub/OpenBSD/patches/2.8.tar.gz">tar.gz file</a>
for convenience.
<p>
Patches for supported releases are also incorporated into the
<a href="stable.html">-stable branch</a>.

<i>All architectures</i><br>
A security hole exists in <a href="https://man.openbsd.org/OpenBSD-2.8/uuxqt.8">uuxqt(8)</a>
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 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.

<i>All architectures</i><br>
A security hole exists in <a href="https://man.openbsd.org/OpenBSD-2.8/lpd.8">lpd(8)</a>
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 security hole exists in <a href="https://man.openbsd.org/OpenBSD-2.8/sendmail.8">sendmail(8)</a>
that may allow an attacker on the local host to gain root privileges by

<li id="kernexec">
<font color="#009000"><strong>030: SECURITY FIX: June 15, 2001</strong></font>
<i>All architectures</i><br>
A race condition exists in the kernel <a href="https://man.openbsd.org/OpenBSD-2.8/execve.2">execve(2)</a> implementation that opens a small window of vulnerability for a non-privileged user to <a href="https://man.openbsd.org/OpenBSD-2.8/ptrace.2">ptrace(2)</a> attach to a suid/sgid process.

<li id="fts">
<font color="#009000"><strong>029: SECURITY FIX: May 30, 2001</strong></font>
<i>All architectures</i><br>
Programs using the <a href="https://man.openbsd.org/OpenBSD-2.8/fts.3">fts(3)</a>
routines (such as rm, find, and most programs that take a <b>-R</b>
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.

This is the second version of the patch.

<li id="sendmail">
<font color="#009000"><strong>028: SECURITY FIX: May 29, 2001</strong></font>
<i>All architectures</i><br>
The signal handlers in <a href="https://man.openbsd.org/OpenBSD-2.8/sendmail.8">sendmail(8)</a> 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).<br>

IPF has a serious problem with fragment caching, the bug is triggered if you use the ipf(5) syntax "keep state".<br>

<a href="https://man.openbsd.org/OpenBSD-2.8/glob.3">ftpd(8)</a> has a potential DoS related to <a href="https://man.openbsd.org/OpenBSD-2.8/glob.3">glob(3)</a>.

<li id="readline">
<font color="#009000"><strong>024: SECURITY FIX: Mar 18, 2001</strong></font>
<i>All architectures</i><br>
The readline library shipped with OpenBSD allows history files creation
with a permissive
<a href="https://man.openbsd.org/OpenBSD-2.8/umask.2">umask(2)</a>.
This can lead to the leakage of sensitive information in applications
that use passwords and the like during user interaction (one such
application is mysql).<br>

Insufficient checks in the IPSEC AH IPv4 option handling code can lead to a buffer overrun leading to a remote DoS. This option is not on by default.<br>

Client side ident protocol was broken in libwrap, affecting anything using libwrap including <a href="https://man.openbsd.org/OpenBSD-2.8/tcpd.8">tcpd</a>. The effect of this was that libwrap would never retrieve and log ident values from remote hosts on connections.<br>

Two problems have recently been discovered in the KerberosIV code.<p>
1. A symlink problem was discovered in the KerberosIV password checking
routines /usr/bin/su and /usr/bin/login, which makes it possible for a
local user to overwrite any file on the local machine.<p>
2. It is possible to specify environment variables in telnet
which will be passed over the to the remote host. This makes it
possible to set environment variables on the remote side, including
ones that have special meaning on the server. It is not clear at this
time what the impact is, but we recommend everyone to upgrade their
machines immediately.<p>

On some machines, a PCIBIOS device driver interrupt allocation bug can cause a
kernel hang while probing PCI devices. If you have this symptom, you can disable
PCIBIOS as a workaround. To do this,
<ul>
<li>Enter the User Kernel Configuration by booting with the
option "boot -c".
<li>Once at the <i>UKC></i> prompt, enter
<blockquote><pre>
UKC> disable pcibios
UKC> quit<!--
--></pre></blockquote>
<li>See <a href="./faq/faq5.html#5.6">this page</a> after a successful
boot for instructions on how to re-write your kernel to disable PCIBIOS
permanently.
