This update fixes several vulnerabilities in imagemagick, a graphical software suite. Various memory handling problems or issues about incomplete input sanitizing would result in denial of service or memory disclosure.
For the oldstable distribution (jessie), these problems have been fixed in version 8:6.8.9.9-5+deb8u12.
We recommend that you upgrade your imagemagick packages.
