TITLE:
QNX Momentics "phgrafx" Privilege Escalation

SECUNIA ADVISORY ID:
SA30808

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.
