This vulnerability has a CVSS 2.0 base score of 6.2, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
The NFSv4 ID mapper (nfsidmap) before 0.17 does not properly handle return values from the getpwnam_r function when performing a username lookup, which can cause it to report a file as being owned by "root" instead of "nobody" if the file exists on the server but not on the client.
Remediation
Check the references section for vendor advisories and patches from nfsv4. Update nfsidmap to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
