CVE-2019-19949: Buffer Overflow

First published: Tue Dec 24 2019(Updated: )

ImageMagick is vulnerable to a heap-based buffer overflow, caused by a flaw in the WritePNGImage function in coders/png.c. By persuading a victim to open a specially-crafted file, a remote attacker could overflow a buffer and execute arbitrary code on the system.
