(CVE-2014-1477, CVE-2014-1478)

Cody Crews discovered a method to bypass System Only Wrappers. An attacker could potentially exploit this to steal confidential data or execute code with the privileges of the user invoking Firefox.
(CVE-2014-1479)

Jordi Chancel discovered that the downloads dialog did not implement a security timeout before button presses are processed. An attacker could potentially exploit this to conduct clickjacking attacks.
(CVE-2014-1480)

Soeren Balko discovered a crash in Firefox when terminating web workers running asm.js code in some circumstances. An attacker could potentially exploit this to execute arbitrary code with the priviliges of the user invoking Firefox. (CVE-2014-1488)

Several issues were discovered with ticket handling in NSS. An attacker could potentially exploit these to cause a denial of service or bypass cryptographic protection mechanisms. (CVE-2014-1490, CVE-2014-1491)

Boris Zbarsky discovered that security restrictions on window objects could be bypassed under certain circumstances. (CVE-2014-1481).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The installed version of Thunderbird is earlier than 24.3 and is, therefore, potentially affected by the following vulnerabilities :

  - Memory issues exist in the browser engine that could     result in a denial of service or arbitrary code     execution. (CVE-2014-1477)

  - An error exists related to System Only Wrappers (SOW)     and the XML Binding Language (XBL) that could allow     XUL content to be disclosed. (CVE-2014-1479)

  - An error exists related to the JavaScript engine and     'window' object handling that has unspecified impact.
    (CVE-2014-1481)

  - An error exists related to 'RasterImage' and image     decoding that could allow application crashes and     possibly arbitrary code execution. (CVE-2014-1482)

  - A use-after-free error exists related to image handling     and 'imgRequestProxy' that could allow application     crashes and possibly arbitrary code execution.
    (CVE-2014-1486)

  - An error exists related to 'web workers' that could     allow cross-origin information disclosure.
    (CVE-2014-1487)

  - Network Security Services (NSS) contains a race     condition in libssl that occurs during session ticket     processing. A remote attacker can exploit this flaw     to cause a denial of service. (CVE-2014-1490)

  - Network Security Services (NSS) does not properly     restrict public values in Diffie-Hellman key exchanges,     allowing a remote attacker to bypass cryptographic     protection mechanisms. (CVE-2014-1491)

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 important 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-2014-1477, CVE-2014-1482, CVE-2014-1486)

A flaw was found in the way Thunderbird handled error messages related to web workers. An attacker could use this flaw to bypass the same-origin policy, which could lead to cross-site scripting (XSS) attacks, or could potentially be used to gather authentication tokens and other data from third-party websites. (CVE-2014-1487)

A flaw was found in the implementation of System Only Wrappers (SOW).
An attacker could use this flaw to crash Thunderbird. When combined with other vulnerabilities, this flaw could have additional security implications. (CVE-2014-1479)

It was found that the Thunderbird JavaScript engine incorrectly handled window objects. A remote attacker could use this flaw to bypass certain security checks and possibly execute arbitrary code.
(CVE-2014-1481)

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Christian Holler, Terrence Cole, Jesse Ruderman, Gary Kwong, Eric Rescorla, Jonathan Kew, Dan Gohman, Ryan VanderMeulen, Sotaro Ikeda, Cody Crews, Fredrik 'Flonka' Lonnqvist, Arthur Gerkis, Masato Kinugawa, and Boris Zbarsky as the original reporters of these issues.

Note: All of the above issues cannot 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.

For technical details regarding these flaws, refer to the Mozilla security advisories for Thunderbird 24.3.0. You can find a link to the Mozilla advisories in the References section of this erratum.

All Thunderbird users should upgrade to this updated package, which contains Thunderbird version 24.3.0, which corrects these issues.
After installing the update, Thunderbird must be restarted for the changes to take effect.

Multiple security issues have been found in Iceweasel, Debian's version of the Mozilla Firefox web browser: Multiple memory safety errors, use-after-frees, too-verbose error messages and missing permission checks may lead to the execution of arbitrary code, the bypass of security checks or information disclosure. This update also addresses security issues in the bundled version of the NSS crypto library.

This update updates Iceweasel to the ESR24 series of Firefox.
