glibc: Stack-based buffer overflow in svcunix_create via long pathnames

Published Jan 14, 2022 CVSS 3.1 · 9.8 Critical EPSS 5.7% KEV · Not listed
Description
The deprecated compatibility function svcunix_create in the sunrpc module of the GNU C Library (aka glibc) through 2.34 copies its path argument on the stack without validating its length, which may result in a buffer overflow, potentially resulting in a denial of service or (if an application is not built with a stack protector enabled) arbitrary code execution.
