CVE-2026-109260

Description

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.
