-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Critical: thunderbird security update Advisory ID: RHSA-2012:0715-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-0715.html Issue date: 2012-06-06 CVE Names: CVE-2011-3101 CVE-2012-1937 CVE-2012-1938 CVE-2012-1939 CVE-2012-1940 CVE-2012-1941 CVE-2012-1944 CVE-2012-1945 CVE-2012-1946 CVE-2012-1947 ===================================================================== 1. Summary: An updated thunderbird package that fixes multiple security issues is now available for Red Hat Enterprise Linux 5 and 6. The Red Hat Security Response Team has rated this update as having critical security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: RHEL Optional Productivity Applications (v. 5 server) - i386, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 3. Description: Mozilla Thunderbird is a standalone mail and newsgroup client. Several flaws were found in the processing of malformed content. Malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2011-3101, CVE-2012-1937, CVE-2012-1938, CVE-2012-1939, CVE-2012-1940, CVE-2012-1941, CVE-2012-1946, CVE-2012-1947) Note: CVE-2011-3101 only affected users of certain NVIDIA display drivers with graphics cards that have hardware acceleration enabled. It was found that the Content Security Policy (CSP) implementation in Thunderbird no longer blocked Thunderbird inline event handlers. Malicious content could possibly bypass intended restrictions if that content relied on CSP to protect against flaws such as cross-site scripting (XSS). (CVE-2012-1944) If a web server hosted content that is stored on a Microsoft Windows share, or a Samba share, loading such content with Thunderbird could result in Windows shortcut files (.lnk) in the same share also being loaded. An attacker could use this flaw to view the contents of local files and directories on the victim's system. This issue also affected users opening content from Microsoft Windows shares, or Samba shares, that are mounted on their systems. (CVE-2012-1945) Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Ken Russell of Google as the original reporter of CVE-2011-3101; Igor Bukanov, Olli Pettay, Boris Zbarsky, and Jesse Ruderman as the original reporters of CVE-2012-1937; Jesse Ruderman, Igor Bukanov, Bill McCloskey, Christian Holler, Andrew McCreight, and Brian Bondy as the original reporters of CVE-2012-1938; Christian Holler as the original reporter of CVE-2012-1939; security researcher Abhishek Arya of Google as the original reporter of CVE-2012-1940, CVE-2012-1941, and CVE-2012-1947; security researcher Arthur Gerkis as the original reporter of CVE-2012-1946; security researcher Adam Barth as the original reporter of CVE-2012-1944; and security researcher Paul Stone as the original reporter of CVE-2012-1945. Note: None of the issues in this advisory can be exploited by a specially-crafted HTML mail message as JavaScript is disabled by default for mail messages. They could be exploited another way in Thunderbird, for example, when viewing the full remote content of an RSS feed. All Thunderbird users should upgrade to this updated package, which contains Thunderbird version 10.0.5 ESR, which corrects these issues. After installing the update, Thunderbird must be restarted for the changes to take effect. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network.
