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

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
