Description

Updated krb5 packages that correct a security flaw are now available for CentOS 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 CentOS 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.
