Synopsis

Description

The remote host is affected by the vulnerability described in GLSA-201207-08 (Gnash: Multiple vulnerabilities)

 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.

Solution

All Gnash users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=www-plugins/gnash-0.8.10-r2'
