Description

USN-2458-1 fixed vulnerabilities in Firefox. This update provides the corresponding version of Ubufox.

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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
