Debian DSA-4549-1 : firefox-esr - security update

high Nessus Plugin ID 130288
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, which could potentially result in the execution of arbitrary code, information disclosure, cross-site scripting or denial of service.

Debian follows the extended support releases (ESR) of Firefox. Support for the 60.x series has ended, so starting with this update we're now following the 68.x releases.

Solution

Upgrade the firefox-esr packages.

For the oldstable distribution (stretch), some additional config changes to the buildd network are needed (to provide the new Rust-based toolchain needed by ESR68). Packages will be made available when those are sorted out.

For the stable distribution (buster), these problems have been fixed in version 68.2.0esr-1~deb10u1.
