Ubuntu Security Notice USN-3761-1
September 06, 2018

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

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

- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS
- Ubuntu 14.04 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, or execute
arbitrary code. (CVE-2018-12375, CVE-2018-12376, CVE-2018-12377,
CVE-2018-12378)

It was discovered that if a user saved passwords before Firefox 58 and
then later set a master password, an unencrypted copy of these passwords
would still be accessible. A local user could exploit this to obtain
sensitive information. (CVE-2018-12383)

Update instructions:

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

Ubuntu 18.04 LTS:
firefox 62.0+build2-0ubuntu0.18.04.3

Ubuntu 16.04 LTS:
firefox 62.0+build2-0ubuntu0.16.04.3

Ubuntu 14.04 LTS:
firefox 62.0+build2-0ubuntu0.14.04.3

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