TITLE:
IBM AIX Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA28609

VERIFY ADVISORY:
http://secunia.com/advisories/28609/

CRITICAL:
Less critical

IMPACT:
Manipulation of data, Exposure of sensitive information, Privilege
escalation

WHERE:
Local system

OPERATING SYSTEM:
AIX 5.x
http://secunia.com/product/213/
AIX 6.x
http://secunia.com/product/16995/

DESCRIPTION:
Some vulnerabilities have been reported in IBM AIX, which can be
exploited by malicious, local users to disclose potentially sensitive
information, manipulate certain files, or gain escalated privileges.

1) A boundary error in the pioout command can be exploited to cause a
buffer overflow and execute arbitrary code with root privileges.

2) An unspecified error in the ps command allows users to access
potentially sensitive information from an arbitrary process.

The vulnerabilities are reported in versions 5.2.0, 5.3.0, 5.3.7, and
6.1.0.

3) Boundary errors in the uspchrp and utape commands can be exploited
by users in the 'system' group to cause a buffer overflow and execute
arbitrary code with root privileges.

The vulnerabilities are reported in versions 5.2.0, 5.3.0, and
5.3.7.

4) Boundary errors in the lchangevg, ldeletepv, putlvodm, lvaryoffvg,
lvgenminor, swap, swapoff, and swapon commands can be exploited by
users in the 'system' group to cause a buffer overflow and execute
arbitrary code with root privileges.

5) The problem is that some of the WebSM Remote Client files are
installed with world-writable permissions, which can be exploited to
e.g. write to the installed files.

The vulnerabilities are reported in version 5.2 and 5.3.
