DESCRIPTION:
A vulnerability has been reported in Blue Coat BCAAA, which can be
exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to an error in the Blue Coat
Authentication and Authorization Agent (BCAAA) when processing
certain packets. This can be exploited to cause a stack-based buffer
overflow via a specially crafted packet sent to TCP port 16102.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is reported in all versions of BCAA associated with
ProxySG releases prior to April 21, 2011 or with a build number prior
to 60258.

SOLUTION:
Currently only a fix for BCAA associated with ProxySG 5.5 is
available in version 5.5.5.1. Restrict access to trusted hosts only.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Paul Harrington, NGS Secure.
