Synopsis
========

Several integer overflows in libjpeg-turbo might allow an attacker to
execute arbitrary code.

Background
==========

libjpeg-turbo is a MMX, SSE, and SSE2 SIMD accelerated JPEG library.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  media-libs/libjpeg-turbo
                                  < 2.0.3                    >= 2.0.3

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

It was discovered that libjpeg-turbo incorrectly handled certain JPEG
images.

Impact
======

A remote attacker could entice a user to open a specially crafted JPEG
file in an application linked against libjpeg-turbo, possibly resulting
in execution of arbitrary code with the privileges of the process or a
Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All libjpeg-turbo users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=media-libs/libjpeg-turbo-2.0.3"
