[DSA-1975-1] Security Support for Debian 4.0 to be discontinued on February 15th

http://seclists.org/fulldisclosure/2010/Jan/397

For anyone still on Debian 4.0, now is a good time to work on a
migration plan to Debian 5.0. Debian will stop releasing security
updates after February 15th for 4.0.

This is also a good time for Ubuntu users to check their distribution
for similar announcements. Ubuntu is based on Debian.

RHEL5 kernel security and bug fix update

https://rhn.redhat.com/errata/RHSA-2010-0046.html

Here is a new kernel update, unrelated to the last update sent out 9
days ago. It fixes a myriad of new problems including Denial of

information leaks to name a few.

It is recommended that RHEL5 systems be updated and rebooted to mitigate
the risk from these issues.

Microsoft Security Advisory (979352) Vulnerability in Internet Explorer Could Allow Remote Code Execution

http://www.microsoft.com/technet/security/advisory/979352.mspx

This is the flaw that was key in the 'Operation Aurora' attack on Google
last week. There are several workarounds that could be employed to help
mitigate the attack.

Running with Internet zone set to High, running with Data Execution
Prevention (DEP) or not running Internet Explorer at all will help to
avoid this issue.
