Package        : imagemagick
CVE ID         : CVE-2017-6498 CVE-2017-6499 CVE-2017-6500
Debian Bug     : 856878 856879 856880 857426 844594

This update fixes several vulnerabilities in imagemagick: Various memory
handling problems and cases of missing or incomplete input sanitising
may result in denial of service or the execution of arbitrary code if
malformed TGA, Sun or PSD files are processed.

This update also fixes visual artefacts when running -sharpen on CMYK
images (no security impact, but piggybacked on top of the security
update with approval of the Debian stable release managers since it's
a regression in jessie compared to wheezy).
 
For the stable distribution (jessie), these problems have been fixed in
version 8:6.8.9.9-5+deb8u8.

For the upcoming stable distribution (stretch), these problems have been
fixed in version 8:6.9.7.4+dfsg-2.

For the unstable distribution (sid), these problems have been fixed in
version 8:6.9.7.4+dfsg-2.

We recommend that you upgrade your imagemagick packages.
