The βkmxfw.sysβ kernel driver included with CAβs Host-Based Intrusion Prevention System (HIPS) or a related security product installed on the remote host is affected by multiple vulnerabilities.
By sending specially crafted IOCTL requests, it may be possible for a local attacker to crash the system or execute arbitrary code with kernel level privileges.
(CVE-2008-2926)
An unspecified flaw may allow a remote attacker to crash the system. (CVE-2008-3174)
