Integer underflow in the Metadata::setData function in MetaData.cpp in libstagefright in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.5 allows remote attackers to execute arbitrary code or cause a denial of service (incorrect memory allocation and application crash) via an MP4 video file with crafted covr metadata that triggers a buffer overflow.

Mozilla: Buffer overflows found through code inspection (MFSA 2015-144)

Buffer overflow in the nsDeque::GrowCapacity function in xpcom/glue/nsDeque.cpp in Mozilla Firefox before 43.0 might allow remote attackers to cause a denial of service or possibly have unspecified other impact by triggering a deque size change.

jquery-ui: XSS vulnerability in jQuery.ui.dialog title option

Cross-site scripting (XSS) vulnerability in jquery.ui.dialog.js in the Dialog widget in jQuery UI before 1.10.0 allows remote attackers to inject arbitrary web script or HTML via the title option.

Mozilla: Buffer overflows found through code inspection (MFSA 2015-144)

openssl: freelist misuse causing a possible use-after-free

Race condition in the ssl3_read_bytes function in s3_pkt.c in OpenSSL through 1.0.1g, when SSL_MODE_RELEASE_BUFFERS is enabled, allows remote attackers to inject data across sessions or cause a denial of service (use-after-free and parsing error) via an SSL connection in a multithreaded environment.

Mozilla: DOS due to malformed frames in HTTP/2 (MFSA 2015-142)

The HTTP/2 implementation in Mozilla Firefox before 43.0 allows remote attackers to cause a denial of service (integer underflow, assertion failure, and application exit) via a malformed PushPromise frame that triggers decompressed-buffer length miscalculation and incorrect memory allocation.

Mozilla: DOS due to malformed frames in HTTP/2 (MFSA 2015-142)

The HTTP/2 implementation in Mozilla Firefox before 43.0 allows remote attackers to cause a denial of service (integer underflow, assertion failure, and application exit) via a single-byte header frame that triggers incorrect memory allocation.

Mozilla: Linux file chooser crashes on malformed JPEG2000 and TGA images due to flaws in underlying libraries (MFSA 2015-143)

The gdk-pixbuf configuration in Mozilla Firefox before 43.0 on Linux GNOME platforms incorrectly enables the TGA decoder, which allows remote attackers to cause a denial of service (heap-based buffer overflow) via a crafted Truevision TGA image.

Mozilla: Linux file chooser crashes on malformed JPEG2000 and TGA images due to flaws in underlying libraries (MFSA 2015-143)

The gdk-pixbuf configuration in Mozilla Firefox before 43.0 on Linux GNOME platforms incorrectly enables the JasPer decoder, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted JPEG 2000 image.

Mozilla: Cross-origin information leak through web workers error events (MFSA 2015-140)

The importScripts function in the Web Workers API implementation in Mozilla Firefox before 43.0 allows remote attackers to bypass the Same Origin Policy by triggering use of the no-cors mode in the fetch API to attempt resource access that throws an exception, leading to information disclosure after a rethrow.

Mozilla: Cross-site reading attack through data: and view-source: URIs (MFSA 2015-149)

Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.5 allow remote attackers to bypass the Same Origin Policy via data: and view-source: URIs.

Mozilla: Integer overflow in MP4 playback in 64-bit versions (MFSA 2015-146)

Integer overflow in the MPEG4Extractor::readMetaData function in MPEG4Extractor.cpp in libstagefright in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.5 on 64-bit platforms allows remote attackers to execute arbitrary code via a crafted MP4 video file that triggers a buffer overflow.

Mozilla: Integer overflow allocating extremely large textures (MFSA 2015-139)

Integer overflow in the mozilla::layers::BufferTextureClient::AllocateForSurface function in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.5 allows remote attackers to execute arbitrary code by triggering a graphics operation that requires a large texture allocation.

Mozilla: Hash in data: URI is incorrectly parsed (MFSA 2015-141)

Mozilla Firefox before 43.0 mishandles the # (number sign) character in a data: URI, which allows remote attackers to spoof web sites via unspecified vectors.

Mozilla: Use-after-free in WebRTC when datachannel is used after being destroyed (MFSA 2015-138)

Use-after-free vulnerability in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.5 allows remote attackers to execute arbitrary code by triggering attempted use of a data channel that has been closed by a WebRTC function.

Mozilla: Firefox allows for control characters to be set in cookies (MFSA 2015-137)

Mozilla Firefox before 43.0 stores cookies containing vertical tab characters, which allows remote attackers to obtain sensitive information by reading HTTP Cookie headers.
