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.
