NVD Description

Note: Versions mentioned in the description apply only to the upstream libnfsidmap package and not the libnfsidmap package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

A flaw was found in nfs-utils. The fsidd daemon improperly handles input received over its local domain socket by relying on program assertions to verify command arguments. A local user can exploit this vulnerability by sending a malformed request lacking the required arguments to trigger an assertion failure. This causes the daemon to crash, resulting in a Denial of Service (DoS) for filesystem identifier lookup services until restarted.
