Synopsis
========

Multiple vulnerabilities have been found in OpenEXR, allowing remote
attackers to execute arbitrary code or cause a Denial of Service
condition.

Background
==========

OpenEXR is a high dynamic-range (HDR) image file format developed by
Industrial Light & Magic for use in computer imaging applications.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  media-libs/openexr           < 1.7.0                    >= 1.7.0

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

Multiple vulnerabilities have been discovered in OpenEXR. Please review
the CVE identifiers referenced below for details.

Impact
======

A context-dependent attacker could execute arbitrary code or cause a
Denial of Service condition via unspecified vectors.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All OpenEXR users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=media-libs/openexr-1.7.0"

Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying some of these
packages.

NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since December 08, 2010. It is likely that your system is
already no longer affected by this issue.
