Description

The ReadJNGImage and ReadOneJNGImage functions in coders/png.c in GraphicsMagick 1.3.26 do not properly manage image pointers after certain error conditions, which allows remote attackers to conduct use-after-free attacks via a crafted file, related to a ReadMNGImage out-of-order CloseBlob call. NOTE: this vulnerability exists because of an incomplete fix for CVE-2017-11403.

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
