The Public Key Pinning (PKP) implementation in Mozilla Firefox before 33.0 skips pinning checks upon an unspecified issuer-verification error, which makes it easier for remote attackers to bypass an intended pinning configuration and spoof a web site via a crafted certificate that leads to presentation of the Untrusted Connection dialog to the user.

The Alarm API in Mozilla Firefox before 33.0 and Firefox ESR 31.x before 31.2 does not properly restrict toJSON calls, which allows remote attackers to bypass the Same Origin Policy via crafted API calls that access sensitive information within the JSON data of an alarm.

The Public Key Pinning (PKP) implementation in Mozilla Firefox before 33.0 does not properly consider the connection-coalescing behavior of SPDY and HTTP/2 in the case of a shared IP address, which allows man-in-the-middle attackers to bypass an intended pinning configuration and spoof a web site by providing a valid certificate from an arbitrary recognized Certification Authority.

Use-after-free vulnerability in DirectionalityUtils.cpp in Mozilla Firefox before 33.0, Firefox ESR 31.x before 31.2, and Thunderbird 31.x before 31.2 allows remote attackers to execute arbitrary code via text that is improperly handled during the interaction between directionality resolution and layout.

Mozilla Firefox before 33.0 does not properly initialize memory for GIF images, which allows remote attackers to obtain sensitive information from process memory via a crafted web page that triggers a sequence of rendering operations for truncated GIF data within a CANVAS element.

The get_tile function in Mozilla Firefox before 33.0, Firefox ESR 31.x before 31.2, and Thunderbird 31.x before 31.2 allows remote attackers to cause a denial of service (out-of-bounds write and application crash) or possibly execute arbitrary code via WebM frames with invalid tile sizes that are improperly handled in buffering operations during video playback.

The mozilla::dom::OscillatorNodeEngine::ComputeCustom function in the Web Audio subsystem in Mozilla Firefox before 33.0, Firefox ESR 31.x before 31.2, and Thunderbird 31.x before 31.2 allows remote attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read, memory corruption, and application crash) via an invalid custom waveform that triggers a calculation of a negative frequency value.

Heap-based buffer overflow in the nsTransformedTextRun function in Mozilla Firefox before 33.0, Firefox ESR 31.x before 31.2, and Thunderbird 31.x before 31.2 allows remote attackers to execute arbitrary code via Cascading Style Sheets (CSS) token sequences that trigger changes to capitalization style.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 33.0 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to improper interaction between threading and garbage collection in the GCRuntime::triggerGC function in js/src/jsgc.cpp, and unknown other vectors.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 33.0, Firefox ESR 31.x before 31.2, and Thunderbird 31.x before 31.2 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Mozilla Network Security Services (NSS) before 3.16.2.1, 3.16.x before 3.16.5, and 3.17.x before 3.17.1, as used in Mozilla Firefox before 32.0.3, Mozilla Firefox ESR 24.x before 24.8.1 and 31.x before 31.1.1, Mozilla Thunderbird before 24.8.1 and 31.x before 31.1.2, Mozilla SeaMonkey before 2.29.1, Google Chrome before 37.0.2062.124 on Windows and OS X, and Google Chrome OS before 37.0.2062.120, does not properly parse ASN.1 values in X.509 certificates, which makes it easier for remote attackers to spoof RSA signatures via a crafted certificate, aka a "signature malleability" issue.

Use-after-free vulnerability in DirectionalityUtils.cpp in Mozilla Firefox before 32.0, Firefox ESR 24.x before 24.8 and 31.x before 31.1, and Thunderbird 24.x before 24.8 and 31.x before 31.1 allows remote attackers to execute arbitrary code via text that is improperly handled during the interaction between directionality resolution and layout.

Mozilla Firefox before 31.1 on Android does not properly restrict copying of local files onto the SD card during processing of file: URLs, which allows attackers to obtain sensitive information from the Firefox profile directory via a crafted application. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-1515.

The mozilla::dom::AudioEventTimeline function in the Web Audio API implementation in Mozilla Firefox before 32.0, Firefox ESR 31.x before 31.1, and Thunderbird 31.x before 31.1 does not properly create audio timelines, which allows remote attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read) via crafted API calls.

Mozilla Firefox before 32.0, Firefox ESR 31.x before 31.1, and Thunderbird 31.x before 31.1 do not properly initialize memory for GIF rendering, which allows remote attackers to obtain sensitive information from process memory via crafted web script that interacts with a CANVAS element associated with a malformed GIF image.

Use-after-free vulnerability in the mozilla::DOMSVGLength::GetTearOff function in Mozilla Firefox before 32.0, Firefox ESR 31.x before 31.1, and Thunderbird 31.x before 31.1 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via an SVG animation with DOM interaction that triggers incorrect cycle collection.

Unspecified vulnerability in the browser engine in Mozilla Firefox before 32.0, Firefox ESR 24.x before 24.8 and 31.x before 31.1, and Thunderbird 24.x before 24.8 and 31.x before 31.1 allows 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 32.0 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 32.0, Firefox ESR 31.x before 31.1, and Thunderbird 31.x before 31.1 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 31.0 does not properly restrict use of drag-and-drop events to spoof customization events, which allows remote attackers to alter the placement of UI icons via crafted JavaScript code that is encountered during (1) page, (2) panel, or (3) toolbar customization.
