icedove - security update

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

For Debian 7 Wheezy, these problems have been fixed in version
45.5.1-1~deb7u1.

We recommend that you upgrade your icedove packages.
