Ubuntu Security Notice USN-3490-1
December 01, 2017

thunderbird vulnerabilities
==========================================================================

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

- Ubuntu 17.10
- Ubuntu 17.04
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in Thunderbird.

Software Description:
- thunderbird: Mozilla Open Source mail and newsgroup client

Details:

Multiple security issues were discovered in Thunderbird. If a user were
tricked in to opening a specially crafted website in a browsing-like
context, an attacker could potentially exploit these to bypass same-origin
restrictions, cause a denial of service via application crash, or execute
arbitrary code. (CVE-2017-7826, CVE-2017-7828, CVE-2017-7830)

Update instructions:

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

Ubuntu 17.10:
  thunderbird                     1:52.5.0+build1-0ubuntu0.17.10.1

Ubuntu 17.04:
  thunderbird                     1:52.5.0+build1-0ubuntu0.17.04.1

Ubuntu 16.04 LTS:
  thunderbird                     1:52.5.0+build1-0ubuntu0.16.04.1

Ubuntu 14.04 LTS:
  thunderbird                     1:52.5.0+build1-0ubuntu0.14.04.1

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