More information:

Multiple security issues have been found in the Mozilla Thunderbird mail client: Multiple memory safety errors, buffer overflows and other implementation errors may lead to the execution of arbitrary code or spoofing.

With version 45.8 Debian drops it's custom branding from the Icedove package and ships the mail client as Thunderbird again. Please see the link below for further information: https://wiki.debian.org/Thunderbird

Transition packages for the Icedove packages are provided which automatically upgrade to the new version. Since new binary packages need to be installed, make sure to allow that in your upgrade procedure (e.g. by using "apt-get dist-upgrade" instead of "apt-get upgrade").

For Debian 7 Wheezy, these problems have been fixed in version 1:45.8.0-3~deb7u1.

We recommend that you upgrade your icedove packages.
