USN-2458-1 fixed vulnerabilities in Firefox. This update introduced a
regression which could make websites that use CSP fail to load under some
circumstances. This update fixes the problem.
We apologize for the inconvenience.
Original advisory 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
Mozilla Firefox before 35.0 and SeaMonkey before 2.32 do not consider the id-pkix-ocsp-nocheck extension in deciding whether to trust an OCSP responder, which makes it easier for remote attackers to obtain sensitive information by sniffing the network during a session in which there was an incorrect decision to accept a compromised and revoked certificate.
Use-after-free vulnerability in the WebRTC implementation in Mozilla Firefox before 35.0, Firefox ESR 31.x before 31.4, and SeaMonkey before 2.32 allows remote attackers to execute arbitrary code via crafted track data.
The mozilla::dom::AudioParamTimeline::AudioNodeInputValue function in the Web Audio API implementation in Mozilla Firefox before 35.0 and SeaMonkey before 2.32 does not properly restrict timeline operations, which allows remote attackers to cause a denial of service (uninitialized-memory read and application crash) via crafted API calls.
Mozilla Firefox before 35.0, Firefox ESR 31.x before 31.4, Thunderbird before 31.4, and SeaMonkey before 2.32 do not properly interpret Set-Cookie headers within responses that have a 407 (aka Proxy Authentication Required) status code, which allows remote HTTP proxy servers to conduct session fixation attacks by providing a cookie name that corresponds to the session cookie of the origin server.
The navigator.sendBeacon implementation in Mozilla Firefox before 35.0, Firefox ESR 31.x before 31.4, Thunderbird before 31.4, and SeaMonkey before 2.32 omits the CORS Origin header, which allows remote attackers to bypass intended CORS access-control checks and conduct cross-site request forgery (CSRF) attacks via a crafted web site.
Mozilla Firefox before 35.0 and SeaMonkey before 2.32 do not properly initialize memory for BMP images, which allows remote attackers to obtain sensitive information from process memory via a crafted web page that triggers the rendering of malformed BMP data within a CANVAS element.
The XrayWrapper implementation in Mozilla Firefox before 35.0 and SeaMonkey before 2.32 does not properly interact with a DOM object that has a named getter, which might allow remote attackers to execute arbitrary JavaScript code with chrome privileges via unspecified vectors.
Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 35.0 and SeaMonkey before 2.32 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 35.0, Firefox ESR 31.x before 31.4, Thunderbird before 31.4, and SeaMonkey before 2.32 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
Mozilla Firefox before 34.0, Firefox ESR 31.x before 31.3, Thunderbird before 31.3, and SeaMonkey before 2.31 might allow remote attackers to execute arbitrary code by leveraging an incorrect cast from the BasicThebesLayer data type to the BasicContainerLayer data type.
Stack-based buffer overflow in the mozilla::FileBlockCache::Read function in Mozilla Firefox before 34.0, Firefox ESR 31.x before 31.3, Thunderbird before 31.3, and SeaMonkey before 2.31 allows remote attackers to execute arbitrary code via crafted media content.
Use-after-free vulnerability in the nsHtml5TreeOperation function in xul.dll in Mozilla Firefox before 34.0, Firefox ESR 31.x before 31.3, Thunderbird before 31.3, and SeaMonkey before 2.31 allows remote attackers to execute arbitrary code by adding a second root element to an HTML5 document during parsing.
Mozilla Firefox 33.0 and SeaMonkey before 2.31 include path strings in CSP violation reports, which allows remote attackers to obtain sensitive information via a web site that receives a report after a redirect.
The XMLHttpRequest.prototype.send method in Mozilla Firefox before 34.0, Firefox ESR 31.x before 31.3, Thunderbird before 31.3, and SeaMonkey before 2.31 allows remote attackers to cause a denial of service (application crash) via a crafted JavaScript object.
Mozilla Firefox before 34.0 and SeaMonkey before 2.31 provide stylesheets with an incorrect primary namespace, which allows remote attackers to bypass intended access restrictions via an XBL binding.
Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 34.0 and SeaMonkey before 2.31 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 34.0, Firefox ESR 31.x before 31.3, Thunderbird before 31.3, and SeaMonkey before 2.31 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
content/base/src/nsDocument.cpp in Mozilla Firefox before 33.0, Firefox ESR 31.x before 31.2, and Thunderbird 31.x before 31.2 does not consider whether WebRTC video sharing is occurring, which allows remote attackers to obtain sensitive information from the local camera in certain IFRAME situations by maintaining a session after the user temporarily navigates away.
The WebRTC video-sharing feature in dom/media/MediaManager.cpp in Mozilla Firefox before 33.0, Firefox ESR 31.x before 31.2, and Thunderbird 31.x before 31.2 does not properly recognize Stop Sharing actions for videos in IFRAME elements, which allows remote attackers to obtain sensitive information from the local camera by maintaining a session after the user tries to discontinue streaming.
