This can be exploited by a local user to access a Kerberized network share without authorisation. 2) An error exists due the nfs_portmon tunable not being correctly utilised in NFSv4. This can be exploited to access network shares protected by nfs_portmon without authorisation. The vulnerabilities are reported in AIX 5.3 and 6.1.
