Mozilla: Improperly initialized memory and overflows in some JavaScript functions (MFSA 2013-96)

The JavaScript engine in Mozilla Firefox before 25.0, Firefox ESR 17.x before 17.0.10 and 24.x before 24.1, Thunderbird before 24.1, Thunderbird ESR 17.x before 17.0.10, and SeaMonkey before 2.22 does not properly allocate memory for unspecified functions, which allows remote attackers to conduct buffer overflow attacks via a crafted web page.

libjpeg: information leak (read of uninitialized memory)

The get_sos function in jdmarker.c in (1) libjpeg 6b and (2) libjpeg-turbo through 1.3.0, as used in Google Chrome before 31.0.1650.48, Ghostscript, and other products, does not check for certain duplications of component data during the reading of segments that follow Start Of Scan (SOS) JPEG markers, which allows remote attackers to obtain sensitive information from uninitialized memory locations via a crafted JPEG image.

Mozilla: Writing to cycle collected object during image decoding (MFSA 2013-97)

The cycle collection (CC) implementation in Mozilla Firefox before 25.0, Firefox ESR 24.x before 24.1, Thunderbird before 24.1, and SeaMonkey before 2.22 does not properly determine the thread for release of an image object, which allows remote attackers to execute arbitrary code or cause a denial of service (race condition and application crash) via a large HTML document containing IMG elements, as demonstrated by the Never-Ending Reddit on reddit.com.

Mozilla: Memory corruption in workers (MFSA 2013-101)

The Worker::SetEventListener function in the Web workers implementation in Mozilla Firefox before 25.0, Firefox ESR 17.x before 17.0.10 and 24.x before 24.1, Thunderbird before 24.1, Thunderbird ESR 17.x before 17.0.10, and SeaMonkey before 2.22 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via vectors related to direct proxies.

The Inter-process Communication (IPC) implementation in Google Chrome before 18.0.1025.168, as used in Mozilla Firefox before 38.0 and other products, does not properly validate messages, which has unspecified impact and attack vectors.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 25.0, Firefox ESR 17.x before 17.0.10 and 24.x before 24.1, Thunderbird before 24.1, Thunderbird ESR 17.x before 17.0.10, and SeaMonkey before 2.22 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:25.0 / rv:124.1) (MFSA 2013-93)

Unspecified vulnerability in the browser engine in Mozilla Firefox before 25.0, Firefox ESR 24.x before 24.1, Thunderbird before 24.1, and SeaMonkey before 2.22 allows 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 in HTML document templates (MFSA 2013-102)

Use-after-free vulnerability in the nsContentUtils::ContentIsHostIncludingDescendantOf function in Mozilla Firefox before 25.0, Firefox ESR 24.x before 24.1, Thunderbird before 24.1, and SeaMonkey before 2.22 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via vectors involving HTML document templates.

Mozilla: Files extracted during updates are not always read only (MFSA 2014-16)

Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 might allow local users to gain privileges by modifying the extracted Mar contents during an update.

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: 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: Out-of-bounds write in Cairo (MFSA 2014-41)

The sse2_composite_src_x888_8888 function in Pixman, as used in Cairo in Mozilla Firefox 28.0 and SeaMonkey 2.25 on Windows, allows remote attackers to execute arbitrary code or cause a denial of service (out-of-bounds write and application crash) by painting on a CANVAS element.

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.

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 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: Miscellaneous memory safety hazards (rv:34.0) (MFSA 2014-83)

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.

Mozilla: XBL bindings accessible via improper CSS declarations (MFSA 2014-84)

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.

Mozilla: Content Security Policy for data: documents not preserved by session restore (MFSA 2014-23)

The session-restore feature in Mozilla Firefox before 28.0 and SeaMonkey before 2.25 does not consider the Content Security Policy of a data: URL, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted document that is accessed after a browser restart.

Mozilla: Spoofing attack on WebRTC permission prompt (MFSA 2014-19)

Mozilla Firefox before 28.0 and SeaMonkey before 2.25 allow remote attackers to spoof the domain name in the WebRTC (1) camera or (2) microphone permission prompt by triggering navigation at a certain time during generation of this prompt.
