Synopsis

The remote Debian host is missing a security-related update.

Description

Multiple security issues have been found in the Mozilla Firefox web browser: Memory safety errors, use-after-frees and other implementation errors may lead to the execution of arbitrary code, information disclosure or privilege escalation.

Solution

Upgrade the firefox-esr packages.

For the stable distribution (jessie), these problems have been fixed in version 45.7.0esr-1~deb8u1.
