Debian DSA-3600-1 : firefox-esr - security update

high Nessus Plugin ID 91550
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

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

Wait, Firefox? No more references to Iceweasel? That's right, Debian no longer applies a custom branding. Please see these links for further information: https://glandium.org/blog/?p=3622, https://en.wikipedia.org/wiki/Mozilla_software_rebranded_by_Debian

Debian follows the extended support releases (ESR) of Firefox. Support for the 38.x series has ended, so starting with this update we're now following the 45.x releases and this update to the next ESR is also the point where we reapply the original branding.

Transition packages for the iceweasel packages are provided which automatically upgrade to the new version. Since new binary packages need to be installed, make sure to allow that in your upgrade procedure (e.g. by using 'apt-get dist-upgrade' instead of 'apt-get upgrade').

Solution

Upgrade the firefox-esr packages.

For the stable distribution (jessie), these problems have been fixed in version 45.2.0esr-1~deb8u1.
