Synopsis
========

A vulnerability in OpenJPEG could result in execution of arbitrary
code.

Background
==========

OpenJPEG is an open-source JPEG 2000 library.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  media-libs/openjpeg          < 1.5.0                    >= 1.5.0

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

An error in jp2.c of OpenJPEG could allow an out-of-bounds write error.

Impact
======

A remote attacker could entice a user to open a specially crafted JPEG
file, possibly resulting in execution of arbitrary code or a Denial of
Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All OpenJPEG users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=media-libs/openjpeg-1.5.0"
