ImageMagick versions before 7.1.2-32 and 6.9.13-57 contain uninitialized heap memory disclosure in the GIF decoder's application extension handler in coders/gif.c. Attackers can craft malicious GIF files that cause the number parser to read uninitialized heap memory and store contents as image metadata, disclosing sensitive heap information.
