"This erratum fixes the remote exploitation of a stack based buffer
overflow vulnerability in Xelerance Corp.'s Openswan, which could
allow attackers to execute arbitrary code.

The vulnerability specifically exists due to a lack of bounds checking
in the pluto application when Openswan is compiled with XAUTH and PAM
support.

The Common Vulnerabilities and Exposures project has assigned the name
CVE-2005-0162 to this problem.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
