DESCRIPTION:
Pasquale Minervini has reported a vulnerability in QNX RTOS, which
potentially can be exploited by malicious, local users to gain
escalated privileges.

The vulnerability is caused due to a boundary error in the suid root
"phgrafx" program. This can be exploited to cause a buffer overflow
via an overly long commandline argument.

Successful exploitation may allow arbitrary code execution with root
privileges.

The vulnerability has been reported in version 6.3.0. Other versions
may also be affected.

SOLUTION:
Grant only trusted users access to affected systems.
