Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

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.
