CVE-2017-5410

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.

Package : icu
CVE ID : CVE-2017-7867 CVE-2017-7868
Debian Bug : 860314

It was discovered that icu, the International Components for Unicode
library, did not correctly validate its input. An attacker could use
this problem to trigger an out-of-bound write through a heap-based
buffer overflow, thus causing a denial of service via application
crash, or potential execution of arbitrary code.

For the stable distribution (jessie), these problems have been fixed in
version 52.1-8+deb8u5.

For the upcoming stable (stretch) and unstable (sid) distributions,
these problems have been fixed in version 57.1-6.

We recommend that you upgrade your icu packages.
