Updated krb5 packages that fix two security flaws 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.
Tenable Network Security discovered a stack-based buffer overflow flaw in the RPC library used by kadmind. 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-2007-3999)
Garrett Wollman discovered an uninitialized pointer flaw in kadmind. A remote unauthenticated attacker who can access kadmind could trigger this flaw and cause kadmind to crash. (CVE-2007-4000)
These issues 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 backported fixes to correct these issues.
