A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 13.10
  • Ubuntu 12.10
  • Ubuntu 12.04 LTS

Summary

Firefox could be made to crash or run programs as your login if it opened a malicious website.

Software Description

Details

Benoit Jacob, Olli Pettay, Jan Varga, Jan de Mooij, Jesse Ruderman, Dan Gohman, Christoph Diehl, Gregor Wagner, Gary Kwong, Luke Wagner, Rob Fletcher and Makoto Kato 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-2014-1493, CVE-2014-1494)

Atte Kettunen discovered an out-of-bounds read during WAV file decoding. An attacker could potentially exploit this to cause a denial of service via application crash. (CVE-2014-1497)

David Keeler discovered that crypto.generateCRFMRequest did not correctly validate all arguments. An attacker could potentially exploit this to cause a denial of service via application crash. (CVE-2014-1498)

Ehsan Akhgari discovered that the WebRTC permission dialog can display the wrong originating site information under some circumstances. An attacker could potentially exploit this by tricking a user in order to gain access to their webcam or microphone. (CVE-2014-1499)

Tim Philipp Schäfers and Sebastian Neef discovered that onbeforeunload events used with page navigations could make the browser unresponsive in some circumstances. An attacker could potentially exploit this to cause a denial of service. (CVE-2014-1500)

Jeff Gilbert discovered that WebGL content could manipulate content from another sites WebGL context. An attacker could potentially exploit this to conduct spoofing attacks. (CVE-2014-1502)

Nicolas Golubovic discovered that CSP could be bypassed for data: documents during session restore. An attacker could potentially exploit this to conduct cross-site scripting attacks. (CVE-2014-1504)

Robert O’Callahan discovered a mechanism for timing attacks involving SVG filters and displacements input to feDisplacementMap. An attacker could potentially exploit this to steal confidential information across domains. (CVE-2014-1505)

Tyson Smith and Jesse Schwartzentruber discovered an out-of-bounds read during polygon rendering in MathML. An attacker could potentially exploit this to steal confidential information across domains. (CVE-2014-1508)

John Thomson discovered a memory corruption bug in the Cairo graphics library. If a user had a malicious extension installed, 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 Firefox. (CVE-2014-1509)

Mariusz Mlynski discovered that web content could open a chrome privileged page and bypass the popup blocker in some circumstances. An attacker could potentially exploit this to execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2014-1510, CVE-2014-1511)

It was discovered that memory pressure during garbage collection resulted in memory corruption in some circumstances. 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 Firefox. (CVE-2014-1512)

Jüri Aedla discovered out-of-bounds reads and writes with TypedArrayObject in some circumstances. 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 Firefox. (CVE-2014-1513)

George Hotz discovered an out-of-bounds write with TypedArrayObject. 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 Firefox. (CVE-2014-1514)
