Scientific Linux Security Update : krb5 on SL6.x i386/x86_64
High Nessus Plugin ID 61157
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionKerberos 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).
Multiple NULL pointer dereference and assertion failure flaws were found in the MIT Kerberos KDC when it was configured to use an LDAP (Lightweight Directory Access Protocol) or Berkeley Database (Berkeley DB) back end. A remote attacker could use these flaws to crash the KDC. (CVE-2011-1527, CVE-2011-1528, CVE-2011-1529)
All krb5 users should upgrade to these updated packages, which contain a backported patch to correct these issues. After installing the updated packages, the krb5kdc daemon will be restarted automatically.
SolutionUpdate the affected packages.
