| powerzip-filename-bo (28534) |  High Risk |
Description:
PowerZip is vulnerable to a stack-based buffer overflow, caused by improper bounds checking of compressed files. By sending a compressed file containing an overly long file name, a remote attacker could overflow a buffer and execute arbitrary code on the system, if the attacker could persuade the victim to open the malicious file.
