CVE-2000-0163 : Detail

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

source: https://www.securityfocus.com/bid/996/info A vulnerability exists in both the ascpu and asmon ports to FreeBSD. Ascpu and asmon are applets for the popular window manager AfterStep. They retain the look and feel of this window manager, and integrate well in to it's "dock" toolbar. As part of the port to FreeBSD, it was deemed necessary to give them access to /dev/kmem, necessitating them being installed setgid kmem. By passing a command line option, it is possible for an attacker to cause these applications to execute arbitrary commands with group 'kmem' privileges. It should be noted that neither of these programs are truly part of FreeBSD. They are not part of any distribution of FreeBSD. Instead, they are part of the 'ports' section. The over 3000 packages included in ports are presented as-is, and in many cases have not been audited for security problems. Exploit: asmon -e "xterm"
