icedove - security update

Multiple security issues have been found in Icedove, Debian’s version of
the Mozilla Thunderbird mail client: Multiple memory safety errors,
buffer overflows and use-after-frees may lead to the execution of
arbitrary code, privilege escalation or denial of service.

For the oldstable distribution (wheezy), these problems have been fixed
in version 31.7.0-1~deb7u1.

For the stable distribution (jessie), these problems have been fixed in
version 31.7.0-1~deb8u1.

For the unstable distribution (sid), these problems will be fixed soon.

We recommend that you upgrade your icedove packages.
