Descriptions
A use-after-free vulnerability in SVG Animation has been discovered. An exploit built on this vulnerability has been discovered in the wild targeting Firefox and Tor Browser users on Windows. This vulnerability affects Firefox < 50.0.2, Firefox ESR < 45.5.1, and Thunderbird < 45.5.1.
Se ha descubierto una vulnerabilidad de uso de memoria previamente liberada en SVG Animation. Se ha descubierto un exploit construido sobre esta vulnerabilidad "in the wild" que apunta a usuarios de Firefox y Tor Browser en Windows. La vulnerabilidad afecta a Firefox en versiones anteriores a la 50.0.2, Firefox ESR en versiones anteriores a la 45.5.1 y Thunderbird en versiones anteriores a la 45.5.1.
A flaw was found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox.
Christian Holler, Jon Coppeard, Olli Pettay, Ehsan Akhgari, Gary Kwong, Tooru Fujisawa, and Randell Jesup discovered multiple memory safety issues in Thunderbird. If a user were tricked in to opening a specially crafted message, an attacker could potentially exploit these to cause a denial of service via application crash, or execute arbitrary code. A same-origin policy bypass was discovered with local HTML files in some circumstances. An attacker could potentially exploit this to obtain sensitive information. Various other issues were also addressed.
Mozilla Firefox, Firefox ESR, and Thunderbird contain a use-after-free vulnerability in SVG Animation, targeting Firefox and Tor browser users on Windows.
