Synopsis
========
libwmf bundles an old GD version which contains a "use-after-free"
vulnerability.
Background
==========
libwmf is a library for converting WMF files.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/libwmf < 0.2.8.4-r3 >= 0.2.8.4-r3
Description
===========
The embedded fork of the GD library introduced a "use-after-free"
vulnerability in a modification which is specific to libwmf.
Impact
======
A remote attacker could entice a user to open a specially crafted WMF
file, possibly resulting in the execution of arbitrary code with the
privileges of the user running the application, or a Denial of Service.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All libwmf users should upgrade to the latest version which no longer
builds the GD library:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/libwmf-0.2.8.4-r3"
References
