The IonMonkey JavaScript engine in Mozilla Firefox before 24.0, Thunderbird before 24.0, and SeaMonkey before 2.21, when Valgrind mode is used, does not properly initialize memory, which makes it easier for remote attackers to obtain sensitive information via unspecified vectors. El motor de JavaScript IonMonkey en Mozilla Firefox anterior a 24.0, Thunderbird anterior a 24.0 y SeaMonkey anterior a 2.21, cuando el modo Valgrind es usado, no inicializa correctamente la memoria, lo que facilita a atacantes remotos obtener información sensible a través de vectores no especificados • http://lists.fedoraproject.org/pipermail/package-announce/2013-September/115907.html http://lists.fedoraproject.org/pipermail/package-announce/2013-September/116610.html http://lists.fedoraproject.org/pipermail/package-announce/2013-September/117526.html http://lists.opensuse.org/opensuse-updates/2013-09/msg00055.html http://lists.opensuse.org/opensuse-updates/2013-09/msg00057.html http://lists.opensuse.org/opensuse-updates/2013-09/msg00059.html http://lists.opensuse.org/opensuse-updates/2013-09/msg00061.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
