Ubuntu 16.04 LTS / 18.04 LTS / 18.10 / 19.04 : ImageMagick vulnerabilities (USN-4034-1)

high Nessus Plugin ID 126254

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

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.

Due to a large number of issues discovered in GhostScript that prevent it from being used by ImageMagick safely, the update for Ubuntu 18.10 and Ubuntu 19.04 includes a default policy change that disables support for the Postscript and PDF formats in ImageMagick. This policy can be overridden if necessary by using an alternate ImageMagick policy configuration.

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.

Solution

Update the affected packages.
