TITLE:
AIX mkvg Insecure Program Execution Vulnerability

SECUNIA ADVISORY ID:
SA21620

VERIFY ADVISORY:
http://secunia.com/advisories/21620/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

OPERATING SYSTEM:
AIX 5.x
http://secunia.com/product/213/

DESCRIPTION:
A security issue has been reported in AIX, which can be exploited by
malicious, local users to gain escalated privileges.

The problem is that mkvg invokes various other programs (chdev,
mkboot, varyonvg, and varyoffvg) without absolute pathnames. This may
be exploited to execute arbitrary code with the privileges of a user
running mkvg by placing a malicious program in the path.

SOLUTION:
Apply APARs.

AIX 5.3:
Apply APAR IY88699.

AIX 5.2:
Apply APAR IY88737.
