tag_insight = "The pam_krb5 module allows Pluggable Authentication Modules (PAM) aware
  applications to use Kerberos to verify user identities by obtaining user
  credentials at log in time.

  A flaw was found in the pam_krb5 "existing_ticket" configuration option. If
  a system is configured to use an existing credential cache via the
  "existing_ticket" option, it may be possible for a local user to gain
  elevated privileges by using a different, local user's credential cache.
  (CVE-2008-3825)
  
  Red Hat would like to thank Stéphane Bertin for responsibly disclosing this
  issue.
  
  Users of pam_krb5 should upgrade to this updated package, which contains a
  backported patch to resolve this issue.";
