Synopsis
========

A buffer overflow vulnerability in Linux Audit may allow local
attackers to execute arbitrary code.

Background
==========

Linux Audit is a set of userspace utilities for storing and processing
auditing records.

Affected packages
=================

~     -------------------------------------------------------------------
~      Package            /  Vulnerable  /                    Unaffected
~     -------------------------------------------------------------------
~   1  sys-process/audit       < 1.7.3                          >= 1.7.3

Description
===========

A stack-based buffer overflow has been reported in the
audit_log_user_command() function in the file lib/audit_logging.c when
processing overly long arguments.

Impact
======

A local attacker could execute a specially crafted command on the host
running Linux Audit, possibly resulting in the execution of arbitrary
code with the privileges of the user running Linux Audit.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Linux Audit users should upgrade to the latest version:

~     # emerge --sync
~     # emerge --ask --oneshot --verbose ">=sys-process/audit-1.7.3"
