Summary

ImageMagick before 6.9.13-57 and from 7.0.0-0 before 7.1.2-32 contains a memory leak in the PNG encoder (CWE-401). The encoder does not release allocated memory when libpng initialization fails. An attacker who can repeatedly trigger PNG encoding in which libpng initialization fails can exhaust memory and cause a denial of service.

Description from the CNA

ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains a memory leak in the PNG encoder, which does not release allocated memory when libpng initialization fails. Attackers who can repeatedly trigger PNG encoding operations in which libpng initialization fails can exhaust memory and cause a denial of service.
