USN-3761-1: Firefox vulnerabilities

6 September 2018

firefox vulnerabilities

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

  o Ubuntu 18.04 LTS
  o Ubuntu 16.04 LTS
  o 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

  o 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

To update your system, please follow these instructions: https://
wiki.ubuntu.com/Security/Upgrades.

necessary changes.
