Microsoft Windows ANI file zero rate number overflow denial of service

win-ani-ratenumber-dos (18667) The risk level is classified as LowLow Risk

Description:

Microsoft Windows are vulnerable to a denial of service. A remote attacker could create a specially-crafted ANI (Windows Animated Cursor) file containing the rate number or frame number set to '0' in the ANI file header, which could cause the Windows Kernel to hang, using considerable resources, once the file is opened. An attacker could exploit this vulnerability by sending the malicious file to a victim as an email attachment or hosting it on a Web page.
