By persuading a victim to open a specially-crafted .CNT file, a remote attacker could overflow a buffer and execute arbitrary code on the system with privileges of the victim. An attacker could exploit this vulnerability by sending the malicious file to a victim as an email attachment or hosting it on a Web site.
