Descriptions

An out of bounds read error occurs when parsing some HTTP digest authorization responses, resulting in information leakage through the reading of random memory containing matches to specifically set patterns. This vulnerability affects Firefox < 52 and Thunderbird < 52.

Ocurre un error de lectura fuera de límites al analizar algunas respuestas HTTP de autorización digest, lo que resulta en una fuga de información mediante la lectura de memoria aleatoria que contiene coincidencias a patrones establecidos específicamente.

USN-3216-1 fixed vulnerabilities in Firefox. The update resulted in a startup crash when Firefox is used with XRDP. This update fixes the problem. Multiple security issues were discovered in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to bypass same origin restrictions, obtain sensitive information, spoof the addressbar, spoof the print dialog, cause a denial of service via application crash or hang, or execute arbitrary code. Various other issues were also addressed.
