Use-after-free vulnerability in the nsEventListenerManager::CompileEventHandlerInternal function in the Event Listener Manager in Mozilla Firefox before 30.0 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via crafted web content.

Versions of Mozilla Firefox ESR prior to 24.6 are unpatched against the following vulnerabilities :

 - Buffer overflows due to insufficient input validation in Gamepad API and Web Audio Speex resampler, which can be leveraged to execute arbitrary code or cause denial of service conditions (CVE-2014-1543, CVE-2014-1542)
 - Use-after-free errors in SMIL Animation Controller, Event Listener Manager, and various other locations, which may be triggered via web content to cause a potentially exploitable crash (CVE-2014-1540, CVE-2014-1539, CVE-2014-1536, CVE-2014-1537)
 - Clickjacking through cursor invisibility when the cursor leaves the embedded flash object (OS X platform only) (CVE-2014-1539)
 - Miscellaneous memory safety hazards (CVE-2014-1533, CVE-2014-1534)

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 installed version of SeaMonkey is a version prior to 2.26.1. It is, therefore, affected by the following vulnerabilities :

  - There are multiple memory safety bugs in the browser     engine. Several of these bugs show evidence of     memory corruption, which may allow an attacker to     execute arbitrary code. (CVE-2014-1533, CVE-2014-1534)

  - There are multiple use-after-free and out of bounds     read issues. These issues have the potential to be     exploited, resulting in remote code execution.
    (CVE-2014-1536, CVE-2014-1537, CVE-2014-1538)

  - A use-after-free error exists in the SMIL Animation     Controller when interacting with and rendering     improperly formed web content. This may result in a     potentially exploitable crash. (CVE-2014-1541)

  - A use-after-free flaw exists in the event listener     manager that can be triggered by web content. This may     result in a potentially exploitable crash.
    (CVE-2014-1540)

  - A flaw exists in the Speex resample in Web Audio that     results in a buffer overflow when working with audio     content that exceeds the expected bounds. This flaw     results in a potentially exploitable crash.
    (CVE-2014-1542)

  - There exists a buffer overflow in the Gamepad API when     it is exercised with a gamepad device with     non-contiguous axes. This flaw results in a potentially     exploitable crash. (CVE-2014-1543)

seamonkey was updated to version 2.26.1 to fix nine security issues.

These security issues were fixed :

  - Miscellaneous memory safety hazards     (CVE-2014-1533/CVE-2014-1534)

  - Use-after-free and out of bounds issues found using     Address Sanitizer     (CVE-2014-1536/CVE-2014-1537/CVE-2014-1538)

  - Use-after-free in Event Listener Manager (CVE-2014-1540)

  - Use-after-free with SMIL Animation Controller     (CVE-2014-1541)

  - Buffer overflow in Web Audio Speex resampler     (CVE-2014-1542)

  - Out of bounds write in NSPR (CVE-2014-1545)

mozilla-nspr was updated to version 4.10.6 to fix one security issue :

  - OOB write with sprintf and console functions     (CVE-2014-1545)

MozillaFirefox was updated to version 30.0 to fix eight security issues :

  - Miscellaneous memory safety hazards     (CVE-2014-1533/CVE-2014-1534)

  - Use-after-free and out of bounds issues found using     Address Sanitizer     (CVE-2014-1536/CVE-2014-1537/CVE-2014-1538)

  - Use-after-free in Event Listener Manager (CVE-2014-1540)

  - Use-after-free with SMIL Animation Controller     (CVE-2014-1541)

  - Buffer overflow in Web Audio Speex resampler     (CVE-2014-1542)

Several non-security bugs were also fixed in this release.

Gary Kwong, Christoph Diehl, Christian Holler, Hannes Verschore, Jan de Mooij, Ryan VanderMeulen, Jeff Walden, Kyle Huey, Jesse Ruderman, Gregor Wagner, Benoit Jacob and Karl Tomlinson discovered multiple memory safety issues in Firefox. If a user were tricked in to opening a specially crafted website, 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 Firefox.
(CVE-2014-1533, CVE-2014-1534)

Abhishek Arya discovered multiple use-after-free and out-of-bounds read issues in Firefox. An attacker could potentially exploit these to cause a denial of service via application crash or execute arbitrary code with the priviliges of the user invoking Firefox. (CVE-2014-1536, CVE-2014-1537, CVE-2014-1538)

Tyson Smith and Jesse Schwartzentruber discovered a use-after-free in the event listener manager. An attacker could potentially exploit this to cause a denial of service via application crash or execute arbitrary code with the priviliges of the user invoking Firefox.
(CVE-2014-1540)

A use-after-free was discovered in the SMIL animation controller. An attacker could potentially exploit this to cause a denial of service via application crash or execute arbitrary code with the priviliges of the user invoking Firefox. (CVE-2014-1541)

Holger Fuhrmannek discovered a buffer overflow in Web Audio. An attacker could potentially exploit this to cause a denial of service via application crash or execute arbitrary code with the priviliges of the user invoking Firefox. (CVE-2014-1542).
