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 same
origin protections, or execute arbitrary code.

Update instructions

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

Ubuntu 18.10

• firefox - 65.0.1+build2-0ubuntu0.18.10.1

Ubuntu 18.04

• firefox - 65.0.1+build2-0ubuntu0.18.04.1

• firefox - 65.0.1+build2-0ubuntu0.16.04.1

Ubuntu 14.04

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