CVE-2015-4479

Múltiples vulnerabilidades de desbordamientos de enteros en libstagefright de Mozilla Firefox en versiones anteriores a 40.0 y Firefox ESR 38.x en versiones anteriores a 38.2, permite a atacantes remotos ejecutar código arbitrario a través de un fragmento saio manipulado en datos de vídeo en MPEG-4.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Mozilla Firefox. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the handling of MPEG4 media files. The issue lies in the failure to check for an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute arbitrary code within the context of the current process.

Gary Kwong, Christian Holler, Byron Campen, Tyson Smith, Bobby Holley, Chris Coulson, and Eric Rahm 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. Aki Helin discovered an out-of-bounds read when playing malformed MP3 content in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to obtain sensitive information, cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Firefox. Various other issues were also addressed.
