Details

Updated krb5 packages that fix several security flaws are now available for
Red Hat Enterprise Linux 4 and 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.

David Coffey discovered an uninitialized pointer free flaw in the RPC
library used by kadmind. On Red Hat Enterprise Linux 4 and 5, glibc
detects attempts to free invalid pointers. A remote unauthenticated
attacker who can access kadmind could trigger this flaw and cause kadmind
to crash. (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)

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

Solution

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
