USN-4988-1: ImageMagick vulnerabilities
15 June 2021
Several security issues were fixed in ImageMagick.
Releases
o Ubuntu 20.10
o Ubuntu 20.04 LTS
o Ubuntu 18.04 LTS
Packages
o 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.

The problem can be corrected by updating your system to the following package
versions:
