http://secunia.com/advisories/30349/

CRITICAL:
Less critical

IMPACT:
Privilege escalation, DoS

WHERE:
Local system

OPERATING SYSTEM:

DESCRIPTION:
Some vulnerabilities have been reported in IBM AIX, which can be
exploited by malicious, local users to cause a DoS (Denial of
Service) or gain escalated privileges.

1) A boundary error within the AIX kernel can be exploited to cause a
buffer overflow and execute arbitrary code with kernel privileges.

2) A boundary error within the setuid root errpt command can be
exploited to cause a buffer overflow and execute arbitrary code with
root privileges.

3) An error within the setuid root iostat command when handling
certain environment variables can be exploited to execute arbitrary
code with root privileges.

The vulnerabilities are reported in versions 5.2, 5.3, and 6.1.
