firefox vulnerabilities

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

• Ubuntu 14.10
• Ubuntu 14.04 LTS
• 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

• firefox
  – Mozilla Open Source web browser

Details

Christian Holler, Patrick McManus, Christoph Diehl, Gary Kwong, Jesse
Ruderman, Byron Campen, Terrence Cole, and Nils Ohlmeier 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-2014-8634, CVE-2014-8635)

Bobby Holley discovered that some DOM objects with certain properties
can bypass XrayWrappers in some circumstances. If a user were tricked in
to opening a specially crafted website, an attacker could potentially
exploit this to bypass security restrictions. (CVE-2014-8636)

Michal Zalewski discovered a use of uninitialized memory when rendering
malformed bitmap images on a canvas element. If a user were tricked in to
opening a specially crafted website, an attacker could potentially
exploit this to steal confidential information. (CVE-2014-8637)

Muneaki Nishimura discovered that requests from navigator.sendBeacon()
lack an origin header. If a user were tricked in to opening a specially
crafted website, an attacker could potentially exploit this to conduct
cross-site request forgery (XSRF) attacks. (CVE-2014-8638)

Xiaofeng Zheng discovered that a web proxy returning a 407 response
could inject cookies in to the originally requested domain. If a user
connected to a malicious web proxy, an attacker could potentially exploit
this to conduct session-fixation attacks. (CVE-2014-8639)

Holger Fuhrmannek discovered a crash in Web Audio while manipulating
timelines. If a user were tricked in to opening a specially crafted
website, an attacker could potentially exploit this to cause a denial
of service. (CVE-2014-8640)

Mitchell Harper discovered a use-after-free in WebRTC. If a user were
tricked in to opening a specially crafted website, 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-2014-8641)

Brian Smith discovered that OCSP responses would fail to verify if signed
by a delegated OCSP responder certificate with the id-pkix-ocsp-nocheck
extension, potentially allowing a user to connect to a site with a revoked
certificate. (CVE-2014-8642)

Update instructions

The problem can be corrected by updating your system to the following
package version:

Ubuntu 14.10:

firefox

35.0+build3-0ubuntu0.14.10.2

Ubuntu 14.04 LTS:

firefox
