- CWE-416
Description
ImageMagick before 7.1.2-15 and 6.9.13-40 contains a heap use-after-free in the meta coder: when memory allocation fails, a single byte is written to a stale pointer. Remote attackers can trigger it by processing specially crafted image files, causing a denial of service.
Affected configurations
• imagemagick imagemagick (< 6.9.13-40)
• imagemagick imagemagick (>= 7.0.0-0 < 7.1.2-15)
