<font color="#009000"><strong>001: RELIABILITY FIX: November 29, 2012</strong></font> &nbsp; <i>All architectures</i><br>
Some other systems have started sending incorrect flags which
cause session failures in OpenBSD's bgpd, and cause it
to propagate incorrect updates.
<br>
<a href="http://ftp.openbsd.org/pub/OpenBSD/patches/5.2/common/001_bgpd.patch">
A source code patch exists which remedies this problem.</a>

<li><a name="002_bgpd"></a>
<font color="#009000"><strong>002: RELIABILITY FIX: March 15, 2013</strong></font> &nbsp; <i>All architectures</i><br>
A rare condition during session startup may cause bgpd to replace
an active session leading to unknown consequences.  Bug found by
inspection (we do not know how to reproduce it, consider that a challenge).

<font color="#009000"><strong>003: RELIABILITY FIX: March 21, 2013</strong></font> &nbsp; <i>All architectures</i><br>
A denial of services was discovered where certain combinations of
TFTP options could cause OACK generation to fail, which in turn
caused a double free in tftpd.

<li><a name="004_nginx"></a>
<font color="#009000"><strong>004: RELIABILITY FIX: May 17, 2013</strong></font> &nbsp; <i>All architectures</i><br>
A problem exists in
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=nginx&sektion=8">nginx(8)</a>
if proxy_pass is used with untrusted HTTP backend servers.
The problem may lead to a denial of service or a disclosure of a
worker process memory on a specially crafted response from an
upstream proxied server.
This issue was assigned CVE-2013-2070.

<font color="#009000"><strong>005: RELIABILITY FIX: May 31, 2013</strong></font> &nbsp; <i>All architectures</i><br>
A local denial of service is possible by an unprivileged user if the
SIOCSIFADDR ioctl is performed upon an AF_INET6 socket with a specially
crafted parameter.
