CVE Descriptions

Stack-based buffer overflow in the (1) swpackage and (2) swmodify commands in HP-UX B.11.11 and possibly other versions allows local users to execute arbitrary code via a long -S argument. NOTE: this might be a duplicate of CVE-2006-2574, but the details relating to CVE-2006-2574 are too vague to be certain.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

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.

EPSS Percentile

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.
