Use-after-free vulnerability in the mozilla::DOMSVGLength::GetTearOff function in Mozilla Firefox before 32.0, Firefox ESR 31.x before 31.1, and Thunderbird 31.x before 31.1 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via an SVG animation with DOM interaction that triggers incorrect cycle collection.

Versions of Mozilla Firefox ESR prior to 24.8 are unpatched for the following vulnerabilities :

 - Use-after-free vulnerabilities -- when setting text direction, and when interacting with SVG content through the DOM -- which can be leveraged for arbitrary code execution (CVE-2014-1567, CVE-2014-1563)
 - Out-of-bounds read in the Web Audio audio timeline that can trigger a crash and potentially disclose memory content (CVE-2014-1565)
 - Incomplete memory initialization when rendering a malformed GIF image could expose that memory to scripts via web content using the '<canvas>' feature, resulting in information disclosure (CVE-2014-1564)
 - Other undisclosed memory issues that have since been patched (CVE-2014-1553, CVE-2014-1554, CVE-2014-1562)

The remote host is affected by the vulnerability described in GLSA-201504-01 (Mozilla Products: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Firefox, Thunderbird,       and SeaMonkey. Please review the CVE identifiers referenced below for       details.
  Impact :

    A remote attacker could entice a user to view a specially crafted web       page or email, possibly resulting in execution of arbitrary code or a       Denial of Service condition. Furthermore, a remote attacker may be able       to perform Man-in-the-Middle attacks, obtain sensitive information, spoof       the address bar, conduct clickjacking attacks, bypass security       restrictions and protection mechanisms,  or have other unspecified       impact.
  Workaround :

    There are no known workarounds at this time.

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2330-1 advisory.

    Jan de Mooij, Christian Holler, Karl Tomlinson, Randell Jesup, Gary Kwong, Jesse Ruderman and JW Wang     discovered multiple memory safety issues in Thunderbird. If a user were tricked in to opening a specially     crafted message with scripting enabled, an attacker could potentially exploit these to cause a denial of     service via application crash, or execute arbitrary code with the privileges of the user invoking     Thunderbird. (CVE-2014-1553, CVE-2014-1562)

    Abhishek Arya discovered a use-after-free during DOM interactions with SVG. If a user were tricked in to     opening a specially crafted message with scripting enabled, an attacker could potentially exploit this to     cause a denial of service via application crash or execute arbitrary code with the privileges of the user     invoking Thunderbird. (CVE-2014-1563)

    Michal Zalewski discovered that memory is not initialized properly during GIF rendering in some     circumstances. If a user were tricked in to opening a specially crafted message, an attacker could     potentially exploit this to steal confidential information. (CVE-2014-1564)

    Holger Fuhrmannek discovered an out-of-bounds read in Web Audio. If a user were tricked in to opening a     specially crafted message with scripting enabled, an attacker could potentially exploit this to cause a     denial of service via application crash or steal confidential information. (CVE-2014-1565)

    A use-after-free was discovered during text layout in some circumstances. If a user were tricked in to     opening a specially crafted message with scripting enabled, an attacker could potentially exploit this to     cause a denial of service via application crash or execute arbitrary code with the privileges of the user     invoking Thunderbird. (CVE-2014-1567)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

MozillaThunderbird was updated to Thunderbird 31.1.0 (bnc#894370), fixinfg security issues :

  - MFSA 2014-67/CVE-2014-1553/CVE-2014-1562 Miscellaneous     memory safety hazards

  - MFSA 2014-68/CVE-2014-1563 (bmo#1018524) Use-after-free     during DOM interactions with SVG

  - MFSA 2014-69/CVE-2014-1564 (bmo#1045977) Uninitialized     memory use during GIF rendering

  - MFSA 2014-70/CVE-2014-1565 (bmo#1047831) Out-of-bounds     read in Web Audio audio timeline

  - MFSA 2014-72/CVE-2014-1567 (bmo#1037641) Use-after-free     setting text directionality

  - update to Thunderbird 31.0

  - based on Gecko 31

  - Autocompleting email addresses now matches against any     part of the name or email

  - Composing a mail to a newsgroup will now autocomplete     newsgroup names

  - Insecure NTLM (pre-NTLMv2) authentication disabled

Mozilla Firefox was updated to Firefox 32 fixing security issues and bugs.

Security issues fixed: MFSA 2014-72 / CVE-2014-1567: Security researcher regenrecht reported, via TippingPoint's Zero Day Initiative, a use-after-free during text layout when interacting with the setting of text direction. This results in a use-after-free which can lead to arbitrary code execution.

MFSA 2014-70 / CVE-2014-1565: Security researcher Holger Fuhrmannek discovered an out-of-bounds read during the creation of an audio timeline in Web Audio. This results in a crash and could allow for the reading of random memory values.

MFSA 2014-69 / CVE-2014-1564: Google security researcher Michal Zalewski discovered that when a malformated GIF image is rendered in certain circumstances, memory is not properly initialized before use.
The resulting image then uses this memory during rendering. This could allow for the a script in web content to access this uninitialized memory using the <canvas> feature.

MFSA 2014-68 / CVE-2014-1563: Security researcher Abhishek Arya (Inferno) of the Google Chrome Security Team used the Address Sanitizer tool to discover a use-after-free during cycle collection.
This was found in interactions with the SVG content through the document object model (DOM) with animating SVG content. This leads to a potentially exploitable crash.

MFSA 2014-67: Mozilla developers and community identified and fixed several memory safety bugs in the browser engine used in Firefox and other Mozilla-based products. Some of these bugs showed evidence of memory corruption under certain circumstances, and we presume that with enough effort at least some of these could be exploited to run arbitrary code.

Jan de Mooij reported a memory safety problem that affects Firefox ESR 24.7, ESR 31 and Firefox 31. (CVE-2014-1562)

Christian Holler, Jan de Mooij, Karl Tomlinson, Randell Jesup, Gary Kwong, Jesse Ruderman, and JW Wang reported memory safety problems and crashes that affect Firefox ESR 31 and Firefox 31. (CVE-2014-1553)

Gary Kwong, Christian Holler, and David Weir reported memory safety problems and crashes that affect Firefox 31. (CVE-2014-1554)

Mozilla NSS was updated to 3.16.4: Notable Changes :

  - The following 1024-bit root CA certificate was restored     to allow more time to develop a better transition     strategy for affected sites. It was removed in NSS     3.16.3, but discussion in the     mozilla.dev.security.policy forum led to the decision to     keep this root included longer in order to give website     administrators more time to update their web servers.

  - CN = GTE CyberTrust Global Root

  - In NSS 3.16.3, the 1024-bit 'Entrust.net Secure Server     Certification Authority' root CA certificate was     removed. In NSS 3.16.4, a 2048-bit intermediate CA     certificate has been included, without explicit trust.
    The intention is to mitigate the effects of the previous     removal of the 1024-bit Entrust.net root certificate,     because many public Internet sites still use the     'USERTrust Legacy Secure Server CA' intermediate     certificate that is signed by the 1024-bit Entrust.net     root certificate. The inclusion of the intermediate     certificate is a temporary measure to allow those sites     to function, by allowing them to find a trust path to     another 2048-bit root CA certificate. The temporarily     included intermediate certificate expires November 1,     2015.
