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/3.2.tar.gz">tar.gz file</a>
for convenience.
<p>
Patches for supported releases are also incorporated into the

A fix for an

bug made in 1996 contains an error that could lead to privilege escalation.
For OpenBSD 3.2 the impact is limited since

is setuid daemon, not setuid root.

<a href="http://man.openbsd.org/OpenBSD-3.2/httpd.8">httpd(8)</a> leaks file inode numbers via ETag header as well as child PIDs in multipart MIME boundary generation. This could lead, for example, to NFS exploitation because it uses inode numbers as part of the file handle.<br>

In
<a href="http://man.openbsd.org/OpenBSD-3.2/ssl.8">ssl(8)</a> an information leak can occur via timing by performing a MAC computation
even if incorrect block cipher padding has been found, this is a
countermeasure. Also, check for negative sizes in memory allocation routines.<br>

<i>All architectures</i><br>
A double free in
<a href="http://man.openbsd.org/OpenBSD-3.2/cvs.1">cvs(1)</a>
could allow an attacker to execute code with the privileges of the
user running cvs. This is only an issue when the cvs command is
being run on a user's behalf as a different user. This means that,
in most cases, the issue only exists for cvs configurations that use
the <em>pserver</em> client/server connection method.<br>

A buffer overflow in

could allow an attacker to execute code with the privileges of named.
On OpenBSD, named runs as a non-root user in a chrooted environment
