DESCRIPTION:
A vulnerability has been reported in fwknop, which can be exploited
by malicious users to potentially compromise a vulnerable system.

The vulnerability is caused due to a boundary error in the
"expand_acc_string_list()" function (server/access.c) when handling
certain access requests and can be exploited to cause a stack-based
buffer overflow.

Successful exploitation may allow execution of arbitrary code, but
requires the attacker to have a valid encryption key.

The vulnerability is reported in versions prior to 2.0.3.

SOLUTION:
Update to version 2.0.3.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Fernando Arnaboldi, IOActive.
