Grabit <= 1.7.2 beta 3 NZB file parsing stack overflow Impact: Remote code execution Version: <= 1.7.2 beta 3 Description Grabit is a popular Windows usenet client designed for downloading binary files. It has support for NZB files, which a user would usually acquire from an external source. Version 1.7.2 beta 3 is vulnerable to a stack overflow when parsing DTD references in NZB files. Earlier versions are vulnerable as well. Reliable exploitation is pretty straightforward. Fix I reported this to the author a while ago. He has now released version 1.7.2 beta 4, which fixes the bug.
