Synopsis
========
Multiple vulnerabilities have been found in Gnash which could result in
execution of arbitrary code, Denial of Service, or information
disclosure.
Background
==========
Gnash is a GNU flash movie player that supports many SWF features.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-plugins/gnash < 0.8.10-r2 >= 0.8.10-r2
Description
===========
Multiple vulnerabilities have been found in Gnash:
* The "nsPluginInstance::setupCookies()" function in plugin.cpp creates
world-readable cookies with predictable file names (CVE-2011-4328).
* The "GnashImage::size()" function in GnashImage.h contains an integer
overflow error which could cause a heap-based buffer overflow
(CVE-2012-1175).
Impact
======
A remote attacker could entice a user to open a specially crafted SWF
file, possibly resulting in execution of arbitrary code or a Denial of
Service condition. Furthermore, a local attacker may be able to obtain
sensitive information.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Gnash users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-plugins/gnash-0.8.10-r2"
