  - Firefox target release 38

  - No new functionality is introduced in this release.
    Notable Changes :

  - The following CA certificate had the Websites and Code     Signing trust bits restored to their original state to     allow more time to develop a better transition strategy     for affected sites :

  - OU = Equifax Secure Certificate Authority

  - The following CA certificate was removed :

  - CN = e-Guven Kok Elektronik Sertifika Hizmet Saglayicisi

An updated thunderbird package that fixes multiple security issues is now available for Red Hat Enterprise Linux 5, 6, and 7.

Red Hat Product Security 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 web content. A web page containing malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2015-2708, CVE-2015-2710, CVE-2015-2713)

A heap-based buffer overflow flaw was found in the way Thunderbird processed compressed XML data. An attacker could create specially crafted compressed XML content that, when processed by Thunderbird, could cause it to crash or execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2015-2716)

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.

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Jesse Ruderman, Mats Palmgren, Byron Campen, Steve Fink, Atte Kettunen, Scott Bell, and Ucha Gobejishvili as the original reporters of these issues.

For technical details regarding these flaws, refer to the Mozilla security advisories for Thunderbird 31.7. 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 31.7, which corrects these issues. After installing the update, Thunderbird must be restarted for the changes to take effect.

The version of Thunderbird installed on the remote Windows host is prior to 31.7. It is, therefore, affected by the following vulnerabilities :

  - A privilege escalation vulnerability exists in the     Inter-process Communications (IPC) implementation due     to a failure to validate the identity of a listener     process. (CVE-2011-3079)

  - Multiple memory corruption issues exist within the     browser engine. A remote attacker can exploit these to     corrupt memory and execute arbitrary code.
    (CVE-2015-2708)

  - A buffer overflow condition exists in SVGTextFrame.cpp     when rendering SVG graphics that are combined with     certain CSS properties due to improper validation of     user-supplied input. A remote attacker can exploit this     to cause a heap-based buffer overflow, resulting in the     execution of arbitrary code. (CVE-2015-2710)

  - A use-after-free error exists due to improper processing     of text when vertical text is enabled. A remote attacker     can exploit this to dereference already freed memory.
    (CVE-2015-2713)

  - A buffer overflow condition exists in the     XML_GetBuffer() function in xmlparse.c due to improper     validation of user-supplied input when handling     compressed XML content. An attacker can exploit this to     cause a buffer overflow, resulting in the execution of     arbitrary code. (CVE-2015-2716)

The version of Firefox installed on the remote Windows host is prior to 38.0. It is, therefore, affected by the following vulnerabilities :

  - A privilege escalation vulnerability exists in the     Inter-process Communications (IPC) implementation due     to a failure to validate the identity of a listener     process. (CVE-2011-3079)

  - An issue exists in the Mozilla updater in which DLL     files in the current working directory or Windows     temporary directories will be loaded, allowing the     execution of arbitrary code. (CVE-2015-0833 /     CVE-2015-2720)

  - Multiple memory corruption issues exist within the     browser engine. A remote attacker can exploit these to     corrupt memory and execute arbitrary code.
    (CVE-2015-2708, CVE-2015-2709)

  - A buffer overflow condition exists in SVGTextFrame.cpp     when rendering SVG graphics that are combined with     certain CSS properties due to improper validation of     user-supplied input. A remote attacker can exploit this     to cause a heap-based buffer overflow, resulting in the     execution of arbitrary code. (CVE-2015-2710)     
  - A security bypass vulnerability exists due to the     referrer policy not being enforced in certain situations     when opening links (e.g. using the context menu or a     middle-clicks by mouse). A remote attacker can exploit     this to bypass intended policy settings. (CVE-2015-2711)     
  - An out-of-bounds read and write issue exists in the     CheckHeapLengthCondition() function due to improper     JavaScript validation of heap lengths. A remote attacker     can exploit this, via a specially crafted web page, to     disclose memory contents. (CVE-2015-2712)

  - A use-after-free error exists due to improper processing     of text when vertical text is enabled. A remote attacker     can exploit this to dereference already freed memory.
    (CVE-2015-2713)

  - A use-after-free error exists in the     RegisterCurrentThread() function in nsThreadManager.cpp     due to a race condition related to media decoder threads     created during the shutdown process. A remote attacker     can exploit this to dereference already freed memory.
    (CVE-2015-2715)

  - A buffer overflow condition exists in the     XML_GetBuffer() function in xmlparse.c due to improper     validation of user-supplied input when handling     compressed XML content. An attacker can exploit this to     cause a buffer overflow, resulting in the execution of     arbitrary code. (CVE-2015-2716)

  - An integer overflow condition exists in the parseChunk()     function in MPEG4Extractor.cpp due to improper handling     of MP4 video metadata in chunks. A remote attacker can     exploit this, via specially crafted media content, to     cause a heap-based buffer overflow, resulting in the     execution of arbitrary code. (CVE-2015-2717)

  - A security bypass vulnerability exists in WebChannel.jsm     due to improper handling of message traffic. An     untrusted page hosting a trusted page within an iframe     can intercept webchannel responses for the trusted page.
    This allows a remote attacker, via a specially crafted     web page, to bypass origin restrictions, resulting in     the disclosure of sensitive information. (CVE-2015-2718)

  - Multiple integer overflow conditions exist in the     bundled libstagefright component due to improper     validation of user-supplied input when processing MPEG4     sample metadata. A remote attacker can exploit this, via     specially crafted media content, to execute arbitrary     code. (CVE-2015-4496)

The version of Firefox ESR 31.x installed on the remote Windows host is prior to 31.7. It is, therefore, affected by the following vulnerabilities :
