Description:
Netragard has reported a vulnerability in HP Tru64 Unix, 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:
Apply ERP kits.
