nfs-utils contains the client and daemon implementations for the NFS protocol.
rpc.gssd in nfs-utils is vulnerable to DNS spoofing due to it depending on PTR resolution for GSSAPI authentication, allowing for data to be submitted to a malicious server without the knowledge of the user.
A remote attacker may be able to obtain sensitive information.
There is no known workaround at this time.
All nfs-utils users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-fs/nfs-utils-1.2.8"
