Gentoo Linux Security Advisory

Title: Gnash: Multiple vulnerabilities (GLSA 201207-08)
Severity: normal
Exploitable: local, remote
Date: July 09, 2012
Bug(s): #391283, #408209
ID: 201207-08

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: www-plugins/gnash
Vulnerable: < 0.8.10-r2
Unaffected: >= 0.8.10-r2
Architectures: All supported architectures


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:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=www-plugins/gnash-0.8.10-r2"
