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

- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

Thunderbird could be made to crash or run programs as your login if it
opened a malicious message.

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

Details:

Christian Holler, Carsten Book, Gary Kwong, Jesse Ruderman, Andrew
McCreight, and Phil Ringnalda discovered multiple memory safety issues in
Thunderbird. If a user were tricked in to opening a specially crafted
message, an attacker could potentially exploit these to cause a denial of
service via application crash, or execute arbitrary code. (CVE-2016-2836)

Update instructions:

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

Ubuntu 16.04 LTS:

Ubuntu 12.04 LTS:
  thunderbird                     1:45.3.0+build1-0ubuntu0.12.04.1

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