CVE-2013-7311 is a vulnerability of currently unknown severity. The OSPF implementation in Check Point Gaia OS R75.X and R76 and IPSO OS 6.2 R75.X and R76 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.. EPSS estimates a 0.61% chance of exploitation in the next 30 days.
