TITLE: AIX Multiple Privilege Escalation Vulnerabilities

SECUNIA ADVISORY ID: SA15636

VERIFY ADVISORY: http://secunia.com/advisories/15636/

CRITICAL: Less critical

IMPACT: Privilege escalation

WHERE: Local system

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

DESCRIPTION: CAU has reported multiple vulnerabilities in AIX, which can be exploited by malicious, local users to gain escalated privileges.

1) A boundary error in invscout when processing command line arguments can be exploited to cause a buffer overflow via an overly long string (about 1024 bytes).

Successful exploitation allows execution of arbitrary code with root privileges.

The vulnerability affects AIX 5.1, 5.2, and 5.3.

2) A boundary error in diagTasksWebSM when processing command line arguments can be exploited to cause a buffer overflow via an overly long string.

Successful exploitation allows execution of arbitrary code with root privileges, but requires membership of the "system" group.

The vulnerability affects AIX 5.1, 5.2, and 5.3.

3) A boundary error in getlvname when processing command line arguments can be exploited to cause a buffer overflow via an overly long string.

Successful exploitation allows execution of arbitrary code with root privileges, but requires membership of the "system" group.

The vulnerability affects AIX 5.1, 5.2, and 5.3.

NOTE: Some other issues have also been reported. According to the vendor, one has already been addressed in prior released APARs fixing a similar vulnerability, another is not currently possible to confirm, and the others are currently not believed to be exploitable.

SOLUTION: The vendor recommends setting the file mode bits to "500" to ensure that only root users can run the vulnerable programs.
