firefox vulnerability

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

- Ubuntu 17.10

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


An out-of-bounds write was discovered when processing Vorbis audio data.
If a user were tricked in to opening a specially crafted website, an
attacker could exploit this to cause a denial of service, or execute
arbitrary code. (CVE-2018-5146)

Update instructions:

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