imagemagick - security update

Several buffer overflows were found in Imagemagick, a suite of image
manipulation programs. Processing malformed PSD files could lead to the
execution of arbitrary code.

For the oldstable distribution (squeeze), these problems have been fixed
in version 8:6.6.0.4-3+squeeze4.

For the stable distribution (wheezy), these problems have been fixed in
version 8:6.7.7.10-5+deb7u3.

For the testing distribution (jessie), these problems have been fixed in
version 8:6.7.7.10+dfsg-1.

For the unstable distribution (sid), these problems have been fixed in
version 8:6.7.7.10+dfsg-1.

We recommend that you upgrade your imagemagick packages.
