Description

 A remote overflow exists in InnerMedia's DynaZip as used in multiple products. The 'DUNZIP32.DLL' library fails to perform proper bounds checking resulting in a buffer overflow. With a specially crafted '.zip' file containing a file with an overly long filename, a remote attacker can cause arbitrary code execution resulting in a loss of integrity.
