Descripción:	Summary: The remote host is missing an update for the 'krb5-devel' package(s) announced via the referenced advisory. Vulnerability Insight: Kerberos is a network authentication system which allows clients and servers to authenticate to each other using symmetric encryption and a trusted third-party, the Key Distribution Center (KDC). A NULL pointer dereference flaw was found in the way the MIT Kerberos KDC processed certain TGS (Ticket-granting Server) requests. A remote, authenticated attacker could use this flaw to crash the KDC via a specially-crafted TGS request. (CVE-2011-1530) Red Hat would like to thank the MIT Kerberos project for reporting this issue. All krb5 users should upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the updated packages, the krb5kdc daemon will be restarted automatically. Affected Software/OS: krb5-devel on CentOS 6 Solution: Please install the updated packages. CVSS Score: 6.8 CVSS Vector: AV:N/AC:L/Au:S/C:N/I:N/A:C
