USN-5649-1: Firefox vulnerabilities

30 September 2022

Firefox could be made to crash or run programs as your login if it opened a malicious website.

Releases

Packages

  • 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, bypass Content
Security Policy (CSP) or other security restrictions, conduct session
fixation attacks, or execute arbitrary code.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 20.04
Ubuntu 18.04

After a standard system update you need to restart Firefox to make
all the necessary changes.
