==========================================================================
Ubuntu Security Notice USN-3761-3
September 17, 2018

firefox regressions
==========================================================================

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

- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

USN-3761-1 caused several regressions in Firefox.

Software Description:
- firefox: Mozilla Open Source web browser

Details:

USN-3761-1 fixed vulnerabilities in Firefox. The update caused several
regressions affecting spellchecker dictionaries and search engines, which
were partially fixed by USN-3761-2. This update contains the remaining fix.

We apologize for the inconvenience.

Original advisory 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+build2-0ubuntu0.18.04.5

Ubuntu 16.04 LTS:
   firefox                                                 62.0+build2-0ubuntu0.16.04.5

Ubuntu 14.04 LTS:
   firefox                                                 62.0+build2-0ubuntu0.14.04.5

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