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).

The version of ImageMagick installed on the remote Windows host is 6.x prior to 6.9.7-5 or 7.x prior to 7.0.4-5. It is, therefore, affected by a denial of service vulnerability in the WriteTGAImage() function in coders/tga.c due to improper handling of TGA files. An unauthenticated, remote attacker can exploit this, by convincing a user to convert a specially crafted image to a TGA file, to cause a denial of service condition.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3232-1 advisory.

    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.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Several issues have been discovered in ImageMagick, a popular set of programs and libraries for image manipulation. These issues include denial of service and memory buffer over-read.

For Debian 7 'Wheezy', these problems have been fixed in version 8:6.7.7.10-5+deb7u12.

We recommend that you upgrade your imagemagick packages.

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

Please reference CVE/URL list for details

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An issue was discovered in ImageMagick 6.9.7. Incorrect TGA files could trigger assertion failures, thus     leading to DoS. (CVE-2017-6498)

Note that Nessus relies on the presence of the package as reported by the vendor.
