Ubuntu Security Notice USN-4234-1
January 09, 2020

firefox vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 19.10
- Ubuntu 19.04
- Ubuntu 18.04 LTS
- Ubuntu 16.04 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 in to opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service, obtain sensitive
information, bypass Content Security Policy (CSP) restrictions, conduct
cross-site scripting (XSS) attacks, or execute arbitrary code.

Update instructions:

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

Ubuntu 19.10:
  firefox                         72.0.1+build1-0ubuntu0.19.10.1

Ubuntu 19.04:
  firefox                         72.0.1+build1-0ubuntu0.19.04.1

Ubuntu 18.04 LTS:
  firefox                         72.0.1+build1-0ubuntu0.18.04.1

Ubuntu 16.04 LTS:
  firefox                         72.0.1+build1-0ubuntu0.16.04.1

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