CVE Descriptions

The runtime linker (ld.so) in Solaris 8, 9, and 10 trusts the LD_AUDIT environment variable in setuid or setgid programs, which allows local users to gain privileges by (1) modifying LD_AUDIT to reference malicious code and possibly (2) using a long value for LD_AUDIT.

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.
