A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 21.04 - Ubuntu 20.10 - Ubuntu 20.04 LTS - Ubuntu 18.04 LTS
Summary:
Firefox could be made to crash or run programs as your login if it opened a malicious website.
Software Description: - firefox: Mozilla Open Source web browser
Details:
Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, re-enable camera devices without an additional permission prompt, spoof the browser UI, or execute arbitrary code. (CVE-2021-29959, CVE-2021-29961, CVE-2021-29966, CVE-2021-29967)
It was discovered that filenames printed from private browsing mode were incorrectly retained in preferences. A local attacker could potentially exploit this to obtain sensitive information. (CVE-2021-29960)
