TITLE:
SGI IRIX cpr Arbitrary Library Loading Privilege Escalation
Vulnerability

SECUNIA ADVISORY ID:
SA11721

VERIFY ADVISORY:
http://secunia.com/advisories/11721/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

OPERATING SYSTEM:
SGI IRIX 6.5.x

DESCRIPTION:
Adam Gowdiak has discovered a vulnerability in IRIX, which can be
exploited by malicious, local users to gain escalated privileges.

The problem is that the /usr/sbin/cpr binary reportedly can be forced
to load a user provided library when restarting the checkpointed
process.

Successful exploitation grants root privileges on a vulnerable
system.

SOLUTION:
Update to version 6.5.25, or install appropriate patches.
