Title:RedHat Security Advisory RHSA-2007:0384

The remote host is missing updates announced in
advisory RHSA-2007:0384.

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

David Coffey discovered an uninitialized pointer free 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 or potentially
execute arbitrary code as root. (CVE-2007-2442)

David Coffey also discovered an overflow flaw in the RPC library used by
kadmind. On Red Hat Enterprise Linux, exploitation of this flaw is limited
to a denial of service. A remote unauthenticated attacker who can access
kadmind could trigger this flaw and cause kadmind to crash. (CVE-2007-2443)

A stack buffer overflow flaw was found in kadmind. An authenticated
attacker who can access kadmind could trigger this flaw and potentially
execute arbitrary code on the Kerberos server. (CVE-2007-2798)

For Red Hat Enterprise Linux 2.1, several portability bugs which would lead
to unexpected crashes on the ia64 platform have also been fixed.

Users of krb5-server are advised to update to these erratum packages which
contain backported fixes to correct these issues.

Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
