imagemagick - security update

Numerous vulnerabilities were discovered in ImageMagick, an image
manipulation program. Issues include memory exception, heap, buffer
and stack overflows, out of bound reads and missing checks.

For Debian 7 Wheezy, these problems have been fixed in version
8:6.7.7.10-5+deb7u10.

The exact impact of the vulnerabilities is unknown, as they were
mostly discovered through fuzzing. We still recommend that you upgrade
your imagemagick packages.
