| Description: | 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.
