Test ID:1.3.6.1.4.1.25623.1.0.58943
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2007:0858
Summary:NOSUMMARY
Description:Description:

The remote host is missing updates announced in
advisory RHSA-2007:0858.

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 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.

Solution:
Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
