Ubuntu Security Notice 2060-1 - Michal Zalewski discovered that libjpeg and libjpeg-turbo incorrectly handled certain memory operations. An attacker could use this issue with a specially-crafted JPEG file to possibly expose sensitive information.

Ubuntu Security Notice 2053-1 - Ben Turner, Bobby Holley, Jesse Ruderman and Christian Holler discovered multiple memory safety issues in Thunderbird. If a user were tricked in to opening a specially crafted message with scripting enabled, an attacker could potentially exploit these to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Thunderbird. Tyson Smith and Jesse Schwartzentruber discovered a use-after-free in event listeners. If a user had enabled scripting, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Thunderbird. Various other issues were also addressed.

Ubuntu Security Notice 2052-1 - Ben Turner, Bobby Holley, Jesse Ruderman, Christian Holler and Christoph Diehl 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 of the user invoking Firefox. Myk Melez discovered that the doorhanger notification for web app installation could persist between page navigations. An attacker could potentially exploit this to conduct clickjacking attacks. Various other issues were also addressed.

Red Hat Security Advisory 2013-1803-01 - The libjpeg-turbo package contains a library of functions for manipulating JPEG images. It also contains simple client programs for accessing the libjpeg functions. An uninitialized memory read issue was found in the way libjpeg-turbo decoded images with missing Start Of Scan JPEG markers or Define Huffman Table JPEG markers. A remote attacker could create a specially crafted JPEG image that, when decoded, could possibly lead to a disclosure of potentially sensitive information.

Mandriva Linux Security Advisory 2013-274 - A Heap-based buffer overflow was found in the way libjpeg-turbo decompressed certain corrupt JPEG images in which the component count was erroneously set to a large value. An attacker could create a specially-crafted JPEG image that, when opened, could cause an application using libpng to crash or, possibly, execute arbitrary code with the privileges of the user running the application. libjpeg 6b and libjpeg-turbo will use uninitialized memory when decoding images with missing SOS data for the luminance component in presence of valid chroma data. libjpeg-turbo will use uninitialized memory when handling Huffman tables.

Mandriva Linux Security Advisory 2013-273 - libjpeg 6b and libjpeg-turbo will use uninitialized memory when decoding images with missing SOS data for the luminance component in presence of valid chroma data. libjpeg-turbo will use uninitialized memory when handling Huffman tables.

jpeg6b and some of its optimized clones (e.g., libjpeg-turbo) will use uninitialized memory when decoding images with missing SOS data for the luminance component (Y) in presence of valid chroma data (Cr, Cb).
