It was discovered that ImageMagick incorrectly handled certain malformed image files. If a user or automated system using ImageMagick were tricked into opening a specially crafted image, an attacker could exploit this to cause a denial of service or possibly execute code with the privileges of the user invoking the program.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The version of ImageMagick installed on the remote Windows host is 6.x prior to 6.9.7-8 or 7.x prior to 7.0.4-8. It is, therefore, affected by multiple denial of service vulnerabilities :

  - A NULL pointer dereference flaw exists in the     ReadPSDChannel() function in coders/psd.c due to     improper handling of PSD files. An unauthenticated,     remote attacker can exploit this, by convincing a user     to open a specially crafted PSD file, to cause a denial     of service condition. (CVE-2017-6497)

  - A flaw exists in Magick++/lib/Exception.cpp due to     improper handling of nested exceptions. An     unauthenticated, remote attacker can exploit this to     cause the application to consume excessive resources,     resulting in a denial of service condition.
    (CVE-2017-6499)

  - A NULL pointer dereference flaw exists in the     ReadXCFImage() function in coders/xcf.c due to improper     handling of XCF files. An unauthenticated, remote     attacker can exploit this, by convincing a user to open     a specially crafted XCF file, to cause a denial of     service condition. (CVE-2017-6501)

Please reference CVE/URL list for details

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).
