"Nikolay Ermishkin from the Mail.Ru Security Team and Stewie discovered
several vulnerabilities in ImageMagick, a program suite for image
manipulation. These vulnerabilities, collectively known as
ImageTragick, are the consequence of lack of sanitization of untrusted
input. An attacker with control on the image input could, with the
privileges of the user running the application, execute code
(CVE-2016-3714 ), make HTTP GET or FTP requests (CVE-2016-3718 ), or
delete (CVE-2016-3715 ), move (CVE-2016-3716 ), or read (CVE-2016-3717
) local files.

These vulnerabilities are particularly critical if Imagemagick
processes images coming from remote parties, such as part of a web
service.

The update disables the vulnerable coders (EPHEMERAL, URL, MVG, MSL,
and PLT) and indirect reads via /etc/ImageMagick-6/policy.xml file. In
addition, we introduce extra preventions, including some sanitization
for input filenames in http/https delegates, the full remotion of
PLT/Gnuplot decoder, and the need of explicit reference in the
filename for the insecure coders."
