Debian DSA-3580-1 : imagemagick - security update (ImageTragick)

high Nessus Plugin ID 91175

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the imagemagick packages.

For the stable distribution (jessie), these problems have been fixed in version 8:6.8.9.9-5+deb8u2.
