DESCRIPTION:
A vulnerability has been reported in Linksys WRT54GC, which can be
exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due a boundary error when handling HTTP
POST requests sent to the web-based management interface. This can be
exploited to cause a buffer overflow via an overly long string sent in
a POST request.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is reported in versions prior to 1.06.1.

SOLUTION:
Update to firmware version 1.06.1.
