CVE-2016-2812

Name of the Vulnerable Software and Affected Versions Mozilla Firefox versions prior to 46.0

Description The issue is related to a race condition in the get implementation of the ServiceWorkerManager class in the Service Worker subsystem. This condition arises due to insufficient checking of the resource state when it can be shared. Exploitation of this issue may allow a remote attacker to execute arbitrary code or cause a denial of service, such as a buffer overflow leading to an application crash, by using a specially crafted web site.

Recommendations For versions prior to 46.0, update to version 46.0 or later to resolve the issue. As a temporary workaround, consider restricting access to potentially vulnerable web sites to minimize the risk of exploitation.
