Packages
- firefox - Mozilla Open Source web browser
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, bypass security
restrictions, bypass same-origin restrictions, conduct cross-site
scripting (XSS) attacks, bypass content security policy (CSP) protections,
or execute arbitrary code.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 19.10
Ubuntu 19.04
Ubuntu 18.04
Ubuntu 16.04
After a standard system update you need to restart Firefox to make
all the necessary changes.
