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
Service, Privilege Escalation, kernel panic, file rewrite, and
information leaks to name a few.

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

Thanks,
Brian

Adobe Shockwave Player Four Integer Overflow Vulnerabilities

http://secunia.com/secunia_research/2009-63/

"Affected: Adobe Shockwave Player 11.5.2.602"

"Secunia Research has discovered four vulnerabilities in Adobe
Shockwave Player, which can be exploited by malicious people to
compromise a user's system.

The vulnerabilities are caused by four integer overflow errors
when processing a certain block type. These can be exploited to cause
heap-based buffer overflows via specially crafted Shockwave files.

Microsoft Windows NT #GP Trap Handler Allows Users to Switch Kernel Stack (affects Windows NT through 7)

http://seclists.org/fulldisclosure/2010/Jan/341

"CVE-2010-0232

In order to support BIOS service routines in legacy 16bit applications,
the Windows NT Kernel supports the concept of BIOS calls in the
Virtual-8086 mode monitor code."

"Upon successful exploitation, the kernel stack is switched to an attacker
specified address." This would allow arbitrary code execution with
escalated privileges.
