CVE-2017-1000378 (GCVE-0-2017-1000378)

Vulnerability from cvelistv5 – Published: 2017-06-19 16:00 – Updated: 2024-08-05 22:00

Summary

The NetBSD qsort() function is recursive, and not randomized, an attacker can construct a pathological input array of N elements that causes qsort() to deterministically recurse N/4 times. This allows attackers to consume arbitrary amounts of stack memory and manipulate stack memory to assist in arbitrary code execution attacks. This affects NetBSD 7.1 and possibly earlier versions.

Severity ?
