Summary
ImageMagick has memory leak of watermark Image object in ReadSTEGANOImage on multiple error/early-return paths
Details

Summary

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.

Direct leak of 13512 byte(s) in 1 object(s) allocated from:
