Descriptions
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.
La función get_sos de jdmarker.c en libjpeg 6b y libjpeg-turbo hasta la versión 1.3.0, tal y como se usa en Google Chrome anterior a la versión 31.0.1650.48, Ghostscript y otros productos, no comprueba ciertas duplicaciones de datos de componentes durante la lectura de segmentos que siguen marcadores Start Of Scan (SOS), lo que permite a atacantes remotos obtener información sensible desde localizaciones de memoria sin inicializar a través de una imagen JPEG manipulada.
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.
