CVE-2019-9956: Buffer Overflow
First published: Sat Mar 23 2019(Updated: )
ImageMagick is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the PopHexPixel function in coders/ps.c. By persuading a victim to open a specially-crafted file, a remote attacker could overflow a buffer and execute arbitrary code, or cause a denial of service condtion on the system.
