CentOS Errata and Security Advisory CESA-2007:0384-01
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.
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.
