Revision 1.26, Tue Mar 11 07:02:06 2014 UTC (10 years, 2 months ago) by deraadt
Branch: MAIN
Changes since 1.25: +1 -6 lines
start to get rid of annoying tail at the bottom of each page; browser
back buttons do that fine, and the rest of the text is not very relevant.

Insufficient protection of the trunk interface queues may cause
LACP trunks to fail under load.

<font color="#009000"><strong>010: SECURITY FIX: April 14, 2010</strong></font> <i>All architectures</i><br>
In TLS connections, certain incorrectly formatted records can cause
an OpenSSL client or server to crash due to a read attempt at NULL.

<li><a name="009_mpi"></a>
<font color="#009000"><strong>009: RELIABILITY FIX: April 4, 2010</strong></font> <i>All architectures</i><br>
When updating sensors showing the state of RAID volumes
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=mpi&sektion=4">mpi(4)</a>
allocates temporary memory and then returns it to the kernel as
device memory.
This causes kernel memory usage to be misrepresented, eventually
leading to a denial of service when a resource limit is apparently
reached.

<font color="#009000"><strong>008: RELIABILITY FIX: March 31, 2010</strong></font> <i>All architectures</i><br>
When decrypting packets, the internal decryption functions were not
paranoid enough in checking for underruns, which could potentially
lead to crashes.

<font color="#009000"><strong>007: RELIABILITY FIX: March 12, 2010</strong></font> <i>All architectures</i><br>
Due to a null pointer dereference, it would be possible to crash ftpd when
handling glob(3)'ing requests. This is non-exploitable.

<font color="#009000"><strong>006: SECURITY FIX: March 12, 2010</strong></font> <i>All architectures</i><br>
OpenSSL is susceptible to a buffer overflow due to a failure
to check for NULL returns from bn_wexpand function calls.

<li><a name="005_ptrace"></a>
<font color="#009000"><strong>005: RELIABILITY FIX: January 29, 2010</strong></font> <i>All architectures</i><br>
By using ptrace(2) on an ancestor process, a loop in the process tree
could be created, violating assumptions in other parts of the kernel
and resulting in infinite loops.

<font color="#009000"><strong>004: SECURITY FIX: November 26, 2009</strong></font> <i>All architectures</i><br>
The SSL/TLS protocol is subject to man-in-the-middle attacks related to
renegotiation (see CVE-2009-3555, draft-ietf-tls-renegotiation-00).
OpenSSL permitted this protocol feature by default and had no way to
disable it.

A vulnerability has been found in BIND's named server
(<a href="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0696">CVE-2009-0696</a>).
An attacker could crash a server with a specially crafted dynamic update message to a
zone for which the server is master.
