Description Marian Rehak 2022-02-15 10:34:06 UTC

In order to successfully exploit this vulnerability, the attacker needs to submit a specially crafted SVG to the ImageMagick to let ImageMagick hang forever from reading a file descriptor. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted SVG file.
