Ubuntu 4034-1: ImageMagick Security Advisory - Denial Of Service Risk

ubuntu
Calendar Grey June 25, 2019
Dist Ubuntu Esm H88
Several vulnerabilities within ImageMagick demand immediate patches for Ubuntu users to ensure their system's security and stability.
Several security issues were fixed in ImageMagick.

Summary

Several security issues were fixed in ImageMagick.

Software Description:

- imagemagick: Image manipulation programs and library

Details:

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.
