USN-5855-2: ImageMagick vulnerabilities

USN-5855-1 fixed a vulnerability in ImageMagick. This update provides
the corresponding update for Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu
22.10.

Original advisory details:

It was discovered that ImageMagick incorrectly handled certain PNG images.
If a user or automated system were tricked into opening a specially crafted
PNG file, an attacker could use this issue to cause ImageMagick to stop
responding, resulting in a denial of service, or possibly obtain the
contents of arbitrary files by including them into images.
