Description Tomas Hoger 2010-02-19 09:24:57 EST
quota's good_client() (quota-tools/rquota_svc.c) seems to be based on good_client() used by nfs-utils and portmap and is affected by similar problems as described here:

  https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2008-4552#c8

With certain hosts.{allow,deny} rules, expected host access control restrictions may not be applied correctly.  The problem does not affect configurations that has deny:ALL and only allow access for specific hosts / networks.

The issue was reported and fixed upstream:
