What is CVE-2017-1000378?

The qsort() function in NetBSD is vulnerable due to its recursive and non-randomized nature. Attackers can craft a specific input array that exploits this vulnerability, leading to excessive recursion and consuming significant stack memory. This can pave the way for arbitrary code execution, allowing malicious actors to manipulate the stack and execute unauthorized code. This issue impacts NetBSD version 7.1 and potentially earlier releases.
