Debian DSA-3881-1 : firefox-esr - security update

critical Nessus Plugin ID 100797
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

Several security issues have been found in the Mozilla Firefox web browser: Multiple memory safety errors, use-after-frees, buffer overflows and other implementation errors may lead to the execution of arbitrary code, denial of service or domain spoofing.

Debian follows the extended support releases (ESR) of Firefox. Support for the 45.x series has ended, so starting with this update we're now following the 52.x releases.

Solution

Upgrade the firefox-esr packages.

For the stable distribution (jessie), these problems have been fixed in version 52.2.0esr-1~deb8u1.

For the upcoming stable distribution (stretch), these problems will be fixed soon.
