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"
