Posted Jul 2, 2020

Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 4408-1 - Multiple security issues were discovered in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information, bypass permission prompts, or execute arbitrary code. It was discovered that when performing add-on updates, certificate chains not terminating with built-in roots were silently rejected. This could result in add-ons becoming outdated. Various other issues were also addressed.
