-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 =========================================================================== AUSCERT Security Bulletin ASB-2012.0148 New versions of Mozilla Firefox, Thunderbird, and SeaMonkey fix multiple vulnerabilities. 29 October 2012 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: Firefox Thunderbird SeaMonkey Operating System: Windows UNIX variants (UNIX, Linux, OSX) Mobile Device Impact/Access: Execute Arbitrary Code/Commands -- Remote with User Interaction Access Privileged Data -- Remote with User Interaction Cross-site Scripting -- Remote with User Interaction Resolution: Patch/Upgrade CVE Names: CVE-2012-4196 CVE-2012-4195 CVE-2012-4194 Member content until: Wednesday, November 28 2012 OVERVIEW Multiple vulnerabilities have been fixed in Mozilla Firefox, Thunderbird and in SeaMonkey. [1] IMPACT The vendor has provided the following details about the vulnerabilities: "Note: Thunderbird is only affected by window.location issues through RSS feeds and extensions that load web content." CVE-2012-4194 "Security researcher Mariusz Mlynski reported that the true value of window.location could be shadowed by user content through the use of the valueOf method, which can be combined with some plugins to perform a cross-site scripting (XSS) attack on users." MFSA 2012-90 [2] CVE-2012-4195 "Mozilla security researcher moz_bug_r_a4 discovered that the CheckURL function in window.location can be forced to return the wrong calling document and principal, allowing a cross-site scripting (XSS) attack. There is also the possibility of gaining arbitrary code execution if the attacker can take advantage of an add-on that interacts with the page content." MFSA 2012-90 [2] CVE-2012-4196 "Security researcher Antoine Delignat-Lavaud of the PROSECCO research team at INRIA Paris reported the ability to use property injection by prototype to bypass security wrapper protections on the Location object, allowing the cross-origin reading of the Location object." MFSA 2012-90 [2] MITIGATION Users of the affected versions should upgrade to current versions: - Firefox: 16.0.2 or Firefox ESR 10.0.10 - Thunderbird: 16.0.2 or Thunderbird ESR 10.0.10 - SeaMonkey: 2.13.2 REFERENCES [1] Mozilla Foundation Security Advisories https://www.mozilla.org/security/announce/ [2] Mozilla Foundation Security Advisory 2012-90 http://www.mozilla.org/security/announce/2012/mfsa2012-90.html AusCERT has made every effort to ensure that the information contained in this document is accurate.
