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

Summary:

Firefox could be made to crash or run programs as your login if it
opened a malicious website.

Software Description:

Multiple security issues were discovered in Firefox. If a user were
tricked in to opening a specially crafted website, an attacker could

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