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
Ubuntu 14.04
Ubuntu 12.04

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