IBM i OSPF 6.1, 7.1, 7.2, and 7.3 is vulnerable when a rogue router spoofs its origin. Routing tables are affected by a missing LSA, which may lead to loss of connectivity. IBM X-Force ID: 128379.
The OSPF implementation in IBM i 6.1 and 7.1, in z/OS on zSeries servers, and in Networking Operating System (aka NOS, formerly BLADE Operating System) does not properly validate Link State Advertisement (LSA) type 1 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.
