Description

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.

• CWE-20Improper Input ValidationThe product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
