USN-4165-1: Firefox vulnerabilities

Releases

• Ubuntu 19.10
• Ubuntu 19.04
• Ubuntu 18.04 ESM
• Ubuntu 16.04 ESM

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

• firefox - 70.0+build2-0ubuntu0.19.10.1

Ubuntu 19.04

• firefox - 70.0+build2-0ubuntu0.19.04.1

Ubuntu 18.04

• firefox - 70.0+build2-0ubuntu0.18.04.1

Ubuntu 16.04

• firefox - 70.0+build2-0ubuntu0.16.04.1

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