CWE-264  (opens in a new tab)

How to fix?

Upgrade nfs to version 1.2.4 or higher.

Overview

Affected versions of this package are vulnerable to Access Restriction Bypass. The host_reliable_addrinfo function in support/export/hostname.c in nfs-utils before 1.2.4 does not properly use DNS to verify access to NFS exports, which allows remote attackers to mount filesystems by establishing crafted DNS A and PTR records.
