tag_insight = "The nfs-utils packages provide a daemon for the kernel Network File System
  (NFS) server, and related tools such as the mount.nfs, umount.nfs, and
  showmount programs.

  A flaw was found in the way nfs-utils performed IP based authentication of
  mount requests. In configurations where a directory was exported to a group
  of systems using a DNS wildcard or NIS (Network Information Service)
  netgroup, an attacker could possibly gain access to other directories
  exported to a specific host or subnet, bypassing intended access
  restrictions. (CVE-2011-2500)

  It was found that the mount.nfs tool did not handle certain errors
  correctly when updating the mtab (mounted file systems table) file. A local
  attacker could use this flaw to corrupt the mtab file. (CVE-2011-1749)

  This update also fixes several bugs and adds an enhancement. Documentation
  for these bug fixes and the enhancement will be available shortly from the
  Technical Notes document, linked to in the References section.

  Users of nfs-utils are advised to upgrade to these updated packages, which
  contain backported patches to resolve these issues and add this
  enhancement. After installing this update, the nfs service will be
  restarted automatically.";
