CVE-2015-4041: GNU Coreutils

High severity, CVSS 7.8. EPSS: 0.5% chance of exploitation in the next 30 days.

The keycompare_mb function in sort.c in sort in GNU Coreutils through 8.23 on 64-bit platforms performs a size calculation without considering the number of bytes occupied by multibyte characters, which allows attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via long UTF-8 strings.

Affected products

• GNU Coreutils: up to and including 8.23
