<strong>001: RELIABILITY FIX: November 29, 2012</strong>
|
|
<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.
|
|

<a href="https://ftp.openbsd.org/pub/OpenBSD/patches/5.2/common/001_bgpd.patch">

<strong>002: RELIABILITY FIX: March 15, 2013</strong>
|
|
<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).

<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.

<strong>004: RELIABILITY FIX: May 17, 2013</strong>

<i>All architectures</i><br>
|
|
A problem exists in
|
|
<a href="https://man.openbsd.org/OpenBSD-5.2/nginx.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.

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
