Descriptions

Mozilla Firefox before 42.0 and Firefox ESR 38.x before 38.4 allow remote attackers to bypass the Same Origin Policy for an IP address origin, and conduct cross-site scripting (XSS) attacks, by appending whitespace characters to an IP address string.

Mozilla Firefox en versiones anteriores a 42.0 y Firefox ESR 38.x en versiones anteriores a 38.4 permite a atacantes remotos eludir la Same Origin Policy para un origen dirección IP y realizar ataques de cross-site scripting (XSS), añadiendo caracteres de espacio en blanco a una cadena de dirección IP.

Christian Holler, David Major, Jesse Ruderman, Tyson Smith, Boris Zbarsky, Randell Jesup, Olli Pettay, Karl Tomlinson, Jeff Walden, and Gary Kwong 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 with the privileges of the user invoking Thunderbird. Tyson Smith and David Keeler discovered a use-after-poison and buffer overflow in NSS. 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. Various other issues were also addressed.
