Multiple security issues have been found in Thunderbird, which may lead
to the execution of arbitrary code or denial of service.

Debian follows the extended support releases (ESR) of Thunderbird.
Support for the 45.x series has ended, so starting with this update
we're now following the 52.x releases.

For the oldstable distribution (jessie), these problems have been fixed
in version 1:52.2.1-4~deb8u1.

For the stable distribution (stretch), these problems have been fixed in
version 1:52.2.1-4~deb9u1.

We recommend that you upgrade your icedove packages.
