CVE-2014-1560

Mozilla Firefox anterior a 31.0 y Thunderbird anterior a 31.0 permiten a atacantes remotos causar una denegación de servicio (interrupción del análisis sintáctico de certificados X.509) a través de un certificado manipulado que no utilice la codificación de caracteres ASCII en un contexto requerido.

Christian Holler, David Keeler and Byron Campen 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. Atte Kettunen discovered a buffer overflow when interacting with WebAudio buffers. 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.
