While the NFS client only asks for one attribute (FATTR4_ACL) in the first bitmap word, the NFSv4 protocol allows for the server to return unbounded bitmaps (more than two)." Upstream commit: e5012d1f3861d18c7f3814e757c1c3ab3741dbcd - incomplete, handles only the case when 2 words are expected and 3 are returned Proposed complete upstream patch: http://www.spinics.net/lists/linux-nfs/msg25288.html Reference: https://bugzilla.redhat.com/show_bug.cgi?id=747106 Credit: Andy Adamson Thanks, -- Petr Matousek / Red Hat Security Response Team
