Directory traversal vulnerability in the DeviceStorage API in Mozilla FirefoxOS before 1.2.2 allows attackers to bypass the media sandbox protection mechanism, and read or modify arbitrary files, via a crafted application that uses a relative pathname for a DeviceStorageFile object.

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.

Mozilla: Privileged access to security wrapped protected objects (MFSA 2014-91)

The Chrome Object Wrapper (COW) implementation in Mozilla Firefox before 34.0 and SeaMonkey before 2.31 supports native-interface passing, which allows remote attackers to bypass intended DOM object restrictions via a call to an unspecified method.

nss: RSA PKCS#1 signature verification forgery flaw (MFSA 2014-73)

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.

Mozilla: Miscellaneous memory safety hazards (rv:31.2) (MFSA 2014-74)

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: Miscellaneous memory safety hazards (rv:33.0) (MFSA 2014-74)

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.

Mozilla: Buffer overflow during CSS manipulation (MFSA 2014-75)

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.

Mozilla: Web Audio memory corruption issues with custom waveforms (MFSA 2014-76)

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.

Mozilla: Out-of-bounds write with WebM video (MFSA 2014-77)

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.

Mozilla Firefox before 28.0.1 on Android processes a file: URL by copying a local file onto the SD card, which allows attackers to obtain sensitive information from the Firefox profile directory via a crafted application.

The saltProfileName function in base/GeckoProfileDirectories.java in Mozilla Firefox through 28.0.1 on Android relies on Android's weak approach to seeding the Math.random function, which makes it easier for attackers to bypass a profile-randomization protection mechanism via a crafted application.

Mozilla: Further uninitialized memory use during GIF rendering (MFSA 2014-78)

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.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 29.0 and SeaMonkey before 2.26 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Mozilla: Use-after-free interacting with text directionality (MFSA 2014-79)

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: Web Audio memory corruption issues (MFSA 2014-36)

The mozilla::dom::OscillatorNodeEngine::ComputeCustom function in the Web Audio subsystem in Mozilla Firefox before 29.0 and SeaMonkey before 2.26 allows remote attackers to execute arbitrary code or cause a denial of service (out-of-bounds read, memory corruption, and application crash) via crafted content.

Mozilla: Key pinning bypasses (MFSA 2014-80)

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.

Mozilla: Accessing cross-origin objects via the Alarms API (MFSA 2014-82)

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.

Mozilla: Use-after-free in the Text Track Manager for HTML video (MFSA 2014-39)

The mozilla::dom::TextTrack::AddCue function in Mozilla Firefox before 29.0 and SeaMonkey before 2.26 does not properly perform garbage collection for Text Track Manager variables, which allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free and heap memory corruption) via a crafted VIDEO element in an HTML document.

Mozilla: Debugger can bypass XrayWrappers with JavaScript (MFSA 2014-47)

The XrayWrapper implementation in Mozilla Firefox before 29.0 and SeaMonkey before 2.26 allows user-assisted remote attackers to bypass intended access restrictions via a crafted web site that is visited in the debugger, leading to unwrapping operations and calls to DOM methods on the unwrapped objects.

Mozilla Firefox before 29.0 on Android allows remote attackers to spoof the address bar via crafted JavaScript code that uses DOM events to prevent the reemergence of the actual address bar after scrolling has taken it off of the screen.
