Título:	RedHat Security Advisory RHSA-2002:250
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing updates announced in advisory RHSA-2002:250. A remotely exploitable stack buffer overflow has been found in the Kerberos v4 compatibility administration daemon distributed with the Red Hat Linux krb5 packages. [Updated 09 Jan 2003] Added fixed packages for the Itanium (IA64) architecture. Kerberos is a network authentication system. A stack buffer overflow has been found in the implementation of the Kerberos v4 compatibility administration daemon (kadmind4), which is part of the MIT krb5 distribution. This vulnerability is present in version 1.2.6 and earlier of the MIT krb5 distribution and can be exploited to gain unauthorized root access to a KDC host. The attacker does not need to authenticate to the daemon to successfully perform this attack. kadmind4 is included in the Kerberos packages in Red Hat Linux Advanced Server but is not enabled or used by default. All users of Kerberos are advised to upgrade to these errata packages which contain a backported patch and are not vulnerable to this issue. 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 http://rhn.redhat.com/errata/RHSA-2002-250.html http://web.mit.edu/kerberos/www/advisories/MITKRB5-SA-2002-002-kadm4.txt Risk factor : Critical CVSS Score: 10.0
