Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated krb5 packages that correct a security flaw are now available
for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the
Red Hat Security Response Team.

Kerberos is a network authentication system which allows clients and
servers to authenticate to each other through use of symmetric
encryption and a trusted third party, the KDC. kadmind is the KADM5
administration server.

The MIT Kerberos Team discovered a problem with the originally
published patch for svc_auth_gss.c (CVE-2007-3999). A remote
unauthenticated attacker who can access kadmind could trigger this
flaw and cause kadmind to crash. On Red Hat Enterprise Linux 5 it is
not possible to exploit this flaw to run arbitrary code as the
overflow is blocked by FORTIFY_SOURCE. (CVE-2007-4743)

This issue did not affect the versions of Kerberos distributed with
Red Hat Enterprise Linux 2.1, 3, or 4.

Users of krb5-server are advised to update to these erratum packages
which contain a corrected backported fix for this issue.
