An updated thunderbird package that fixes several 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.

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-2012-3982, CVE-2012-3988, CVE-2012-3990, CVE-2012-3995, CVE-2012-4179, CVE-2012-4180, CVE-2012-4181, CVE-2012-4182, CVE-2012-4183, CVE-2012-4185, CVE-2012-4186, CVE-2012-4187, CVE-2012-4188)

Two flaws in Thunderbird could allow malicious content to bypass intended restrictions, possibly leading to information disclosure, or Thunderbird executing arbitrary code. Note that the information disclosure issue could possibly be combined with other flaws to achieve arbitrary code execution. (CVE-2012-3986, CVE-2012-3991)

Multiple flaws were found in the location object implementation in Thunderbird. Malicious content could be used to perform cross-site scripting attacks, script injection, or spoofing attacks.
(CVE-2012-1956, CVE-2012-3992, CVE-2012-3994)

Two flaws were found in the way Chrome Object Wrappers were implemented. Malicious content could be used to perform cross-site scripting attacks or cause Thunderbird to execute arbitrary code.
(CVE-2012-3993, CVE-2012-4184)

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Christian Holler, Jesse Ruderman, Soroush Dalili, miaubiz, Abhishek Arya, Atte Kettunen, Johnny Stenback, Alice White, moz_bug_r_a4, and Mariusz Mlynski as the original reporters of these issues.

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 10.0.8 ESR, which corrects these issues.
After installing the update, Thunderbird must be restarted for the changes to take effect.

The installed version of Thunderbird 10.0.x is affected by the following vulnerabilities :

  - Several memory safety bugs exist in the browser engine     used in Mozilla-based products that could be exploited     to execute arbitrary code. (CVE-2012-3983)

  - Some methods of a feature used for testing     (DOMWindowUtils) are not properly protected and may be     called through script by web pages. (CVE-2012-3986)

  - A potentially exploitable denial of service may be     caused by a combination of invoking full-screen mode and     navigating backwards in history. (CVE-2012-3988)

  - When the 'GetProperty' function is invoked through JSAP,     security checking can by bypassed when getting cross-     origin properties, potentially allowing arbitrary code     execution. (CVE-2012-3991)

  - The 'location' property can be accessed by binary     plugins through 'top.location' and 'top' can be shadowed     by 'Object.defineProperty', potentially allowing cross-     site scripting attacks through plugins. (CVE-2012-3994)

  - The Chrome Object Wrapper (COW) has flaws that could     allow access to privileged functions, allowing for cross-     site scripting attacks or arbitrary code execution.     (CVE-2012-3993, CVE-2012-4184)

  - The 'location.hash' property is vulnerable to an attack     that could allow an attacker to inject script or     intercept post data. (CVE-2012-3992)

  - The 'Address Sanitizer' tool is affected by multiple,     potentially exploitable use-after-free flaws.     (CVE-2012-3990, CVE-2012-3995, CVE-2012-4179,     CVE-2012-4180, CVE-2012-4181, CVE-2012-4182,     CVE-2012-4183)

  - The 'Address Sanitizer' tool is affected by multiple,     potentially exploitable heap memory corruption issues.     (CVE-2012-4185, CVE-2012-4186, CVE-2012-4187,     CVE-2012-4188)
