CVE-2014-1559

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 UTF-8 en un contexto requerido, una vulnerabilidad diferente a CVE-2014-1558.

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.
