VERIFY ADVISORY:
http://secunia.com/advisories/22451/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

OPERATING SYSTEM:
HP-UX 11.x
http://secunia.com/product/138/

DESCRIPTION:
Netragard has reported a vulnerability in HP-UX, which can be
exploited by malicious, local users to gain escalated privileges.

The vulnerability is caused due to a boundary error in dtmail when
processing arguments to the "-a" command line option. This can be
exploited to cause a buffer overflow by supplying an overly long
string.

Successful exploitation allows execution of arbitrary code with
"mail" group privileges.

SOLUTION:
HP-UX B.11.23:
Install PHSS_35435 or later.

HP-UX B.11.11:
Install PHSS_35434 or later.
