Ubuntu Security Notice USN-4637-1
November 18, 2020

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

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

– 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 in to opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service, obtain sensitive
information across origins, bypass security restrictions, conduct phishing
attacks, conduct cross-site scripting (XSS) attacks, bypass Content
Security Policy (CSP) restrictions, conduct DNS rebinding attacks, or
execute arbitrary code.

Update instructions:

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

Ubuntu 20.10:
firefox 83.0+build2-0ubuntu0.20.10.1

Ubuntu 20.04 LTS:
firefox 83.0+build2-0ubuntu0.20.04.1

Ubuntu 18.04 LTS:
firefox 83.0+build2-0ubuntu0.18.04.2

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