CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

DESCRIPTION:
A vulnerability has been reported in HP Tru64, which can be exploited
by malicious, local users to gain escalated privileges.

The vulnerability is caused due to a boundary error in libpthread
when handling the "PTHREAD_CONFIG" environment variable. This can be
exploited to cause a buffer overflow via a specially crafted data in
the variable.

Successful exploitation may allow execution of arbitrary code with
"root" privileges.
