Vulnerability: Recursive and Non-Randomized qsort() Function in NetBSD

CVE-2017-1000378 · HIGH Severity

AV:N/AC:L/AU:N/C:P/I:P/A:P

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.
