Panda Antivirus and Firewall is vulnerable to a denial of service and system compromise. The kernel driver included with Panda Antivirus and Firewall 2008 does not handle IOCTL requests correctly. This can result in a local denial of service or execution of code on the local system. There is currently a hotfix available for this issue. If you, or anyone you know, runs Panda Antivirus give them a heads up to run the update utility.
