Firefox ESR 31.x < 31.5.3 SVG Bypass Privilege Escalation (Mac OS X)

High Nessus Plugin ID 82035


The remote Mac OS X host contains a web browser that is affected by a privilege escalation vulnerability.


The version of Mozilla Firefox ESR 31.x installed on the remote Mac OS X host is prior to 31.5.3. It is, therefore, affected by a privilege escalation vulnerability due to a flaw within 'docshell/base/nsDocShell.cpp', which relates to SVG format content navigation. A remote attacker can exploit this to bypass same-origin policy protections, allowing a possible execution of arbitrary scripts in a privileged context.


Upgrade to Firefox ESR 31.5.3 or later.
