Scientific Linux Security Update : krb5 on SL6.x i386/x86_64

medium Nessus Plugin ID 61190

Language:

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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)

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.

Solution

Update the affected packages.
