Updated imgagmagick packages fix security vulnerability

Publication date: 11 Apr 2023
Type: security
Affected Mageia releases : 8
CVE: CVE-2023-1289


A vulnerability was discovered in ImageMagick where a specially created
SVG file loads itself and causes a segmentation fault. This flaw allows a
remote attacker to pass a specially crafted SVG file that leads to a
segmentation fault, generating many trash files in "/tmp," resulting in a
denial of service. When ImageMagick crashes, it generates a lot of trash
files. These trash files can be large if the SVG file contains many render
actions. In a denial of service attack, if a remote attacker uploads an
SVG file of size t, ImageMagick generates files of size 103*t. If an
attacker uploads a 100M SVG, the server will generate about 10G.
