CVE-2013-7309: Extremenetworks Exos

Medium severity, CVSS 5.4. EPSS: 1.2% chance of exploitation in the next 30 days.

The OSPF implementation in Extreme Networks EXOS 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.
