Advisory ID: VMSA-2017-0014
Severity:    Important
Synopsis:    VMware NSX-V Edge updates address OSPF Protocol LSA DoS
Issue date:  2017-08-10
Updated on:  2017-08-10 (Initial Advisory)
CVE number:  CVE-2017-4920

1. Summary
   VMware NSX-V Edge updates address OSPF Protocol LSA Denial of
   Service.
2. Relevant Products
   VMware NSX-V Edge
3. Problem Description
   a. VMware NSX-V Edge OSPF Protocol LSA Denial of Service
   VMware NSX-V implementation of the OSPF protocol doesn’t correctly
   handle the link-state advertisement (LSA). A rogue LSA may exploit
   this issue resulting in continuous sending of LSAs between two
   routers eventually going in loop or loss of connectivity.
   Note: The issue cannot be exploited in case the OSPF protocol is not
   configured. At setup time, no particular protocol is configured. For
   more information on static and dynamic routing for NSX Edge refer to
   the NSX Administration Guide, section Logical Router.
   VMware would like to thank Adi Sosnovich, Orna Grumberg and Gabi
   Nakibly for reporting this issue to us.
