Audit Finds No Critical Flaws in Firefox Update System

[silversurfer]

An audit commissioned by Mozilla for the Firefox update system revealed no critical vulnerabilities and the flaws rated "high severity" were not easy to exploit.

Experts at Germany-based X41 spent 27 days analyzing the Firefox Application Update Service (AUS), including its update signing protocol, client code, backend and other components. The audit involved a cryptographic review, fuzzing, pentesting, and manual code analysis.

Mozilla has already patched the serious vulnerabilities and is currently working on addressing the less severe issues and the side findings. The organization has made public the full report from X41 and opened the bug tracker where the patching progress can be monitored.
