Descriptions

Mozilla Firefox before 48.0 and Firefox ESR 45.x before 45.3 allow user-assisted remote attackers to bypass the Same Origin Policy, and conduct Universal XSS (UXSS) attacks or read arbitrary files, by arranging for the presence of a crafted HTML document and a crafted shortcut file in the same local directory.

Mozilla Firefox en versiones anteriores a 48.0 y Firefox ESR 45.x en versiones anteriores a 45.3 permite a atacantes remotos asistidos por usuario eludir el Same Origin Policy, y llevar a cabo ataques Universal XSS (UXSS) o leer archivos arbitrarios, disponiendo la presencia de un documento HTML manipulado y un archivo de acceso directo manipulado en el mismo directorio local.

Gustavo Grieco discovered an out-of-bounds read during XML parsing in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via application crash, or obtain sensitive information. Toni Huttunen discovered that once a favicon is requested from a site, the remote server can keep the network connection open even after the page is closed. A remote attacker could potentially exploit this to track users, resulting in information disclosure. Various other issues were also addressed.
