GHSA-QC88-87CW-XW5J

Vulnerability from github – Published: 2022-05-13 01:41 – Updated: 2022-05-13 01:41

Details

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 ?

9.8 (Critical)
