Mozilla Firefox ESR 52.x < 52.1.1 ANGLE Graphics Library RCE

High Nessus Plugin ID 100126


The remote Windows host contains a web browser that is affected by a remote code execution vulnerability.


The version of Mozilla Firefox ESR installed on the remote Windows host is 52.x prior to 52.1.1. It is, therefore, affected by a use-after-free error in libANGLE/renderer/d3d/d3d11/Buffer11.cpp within the ANGLE graphics library (libGLES) when handling Buffer11 API calls. An unauthenticated remote attacker can exploit this, by convincing a user to visit a specially crafted web page, to dereference already freed memory, resulting in a crash or potentially the execution of arbitrary code.


Upgrade to Mozilla Firefox ESR version 52.1.1 or later.
