CVE-2012-1938

Múltiples vulnerabilidades no especificadas en el motor del navegador de Mozilla Firefox antes de v13.0, Thunderbird antes de v13.0, y SeaMonkey antes de v2.10 permiten a atacantes remotos causar una denegación de servicio (corrupción de la memoria y caída de la aplicación) o posiblemente ejecutar código de su elección a través de vectores relacionados con (1) methodjit/ImmutableSync.cpp, y con la función (2) JSObject::makeDenseArraySlow en js/src/jsarray.cpp y otros componentes desconocidos.

Security issues were identified and fixed in mozilla firefox and thunderbird. Heap-based buffer overflow in the utf16_to_isolatin1 function in Mozilla Firefox 4.x through 12.0, Firefox ESR 10.x before 10.0.5, Thunderbird 5.0 through 12.0, Thunderbird ESR 10.x before 10.0.5, and SeaMonkey before 2.10 allows remote attackers to execute arbitrary code via vectors that trigger a character-set conversion failure. Use-after-free vulnerability in the nsFrameList::FirstChild function in Mozilla Firefox 4.x through 12.0, Firefox ESR 10.x before 10.0.5, Thunderbird 5.0 through 12.0, Thunderbird ESR 10.x before 10.0.5, and SeaMonkey before 2.10 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption and application crash) by changing the size of a container of absolutely positioned elements in a column. Heap-based buffer overflow in the nsHTMLReflowState::CalculateHypotheticalBox function in Mozilla Firefox 4.x through 12.0, Firefox ESR 10.x before 10.0.5, Thunderbird 5.0 through 12.0, Thunderbird ESR 10.x before 10.0.5, and SeaMonkey before 2.10 allows remote attackers to execute arbitrary code by resizing a window displaying absolutely positioned and relatively positioned elements in nested columns. Various other issues were also addressed.
