CVE-2013-7312 is a medium-severity flaw (CVSS 5.4) affecting c5, g3, k10. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

The OSPF implementation on Enterasys switches and routers does not consider the possibility of duplicate Link State ID values in Link State Advertisement (LSA) packets before performing operations on the LSA database, which allows remote attackers to cause a denial of service (routing disruption) or obtain sensitive packet information via a crafted LSA packet, a related issue to CVE-2013-0149.
