firefox vulnerabilities
Details

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. (CVE-2020-12415, CVE-2020-12416, CVE-2020-12417, CVE-2020-12418, CVE-2020-12419, CVE-2020-12420, CVE-2020-12422, CVE-2020-12424, CVE-2020-12425, CVE-2020-12426)

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 This could result in add-ons becoming outdated. (CVE-2020-12421)
