FreeBSD : picasm -- buffer overflow vulnerability (8a3ece40-3315-11da-a263-0001020eed82)

This script is Copyright (C) 2006-2013 Tenable Network Security, Inc.


Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

Shaun Colley reports :

When generating error and warning messages, picasm copies strings into
fixed length buffers without bounds checking.

If an attacker could trick a user into assembling a source file with a
malformed 'error' directive, arbitrary code could be executed with the
privileges of the user. This could result in full system compromise.
