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"
