原文の説明
取得元が公開している説明をそのまま載せています (多くは英語)。
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, in ReadSTEGANOImage() (coders/stegano.c), the watermark Image object is not freed on three early-return paths, resulting in a definite memory leak (~13.5KB+ per invocation) that can be exploited for denial of service. Versions 7.1.2-15 and 6.9.13-40 contain a patch.
