  A Red Hat specific patch used in the openssh packages as shipped in Red
  Hat Enterprise Linux 5.4 (RHSA-2009:1287) loosened certain ownership
  requirements for directories used as arguments for the ChrootDirectory
  configuration options. A malicious user that also has or previously had
  non-chroot shell access to a system could possibly use this flaw to
  escalate their privileges and run commands as any system user.
  (CVE-2009-2904)

  All OpenSSH users are advised to upgrade to these updated packages, which
  contain a backported patch to resolve this issue. After installing this
  update, the OpenSSH server daemon (sshd) will be restarted automatically.");
