TITLE:
QNX Momentics "phgrafx" Privilege Escalation
SECUNIA ADVISORY ID:

VERIFY ADVISORY:
http://secunia.com/advisories/30808/
CRITICAL:
Less critical
IMPACT:
Privilege escalation
WHERE:
Local system
SOFTWARE:
QNX Momentics 6.x
http://secunia.com/product/19229/
DESCRIPTION:
Scanit Labs has reported a vulnerability in QNX Momentics, which can
be exploited by malicious, local users to gain escalated privileges.
The vulnerability is caused due to a boundary error in
/usr/photon/bin/phgrafx when handling .pal files in the
PHOTON_PATH\palette folder. This can be exploited to cause a
stack-based buffer overflow via a .pal file with an overly long
(greater than 285 characters) filename placed in the "palette"
folder.
The vulnerability reportedly affects version 6.3.2 and prior.
SOLUTION:
The vendor recommends clearing the setuid bit for phgrafx.
