Cisco SD-WAN vEdge Routers Denial of Service Vulnerability

A vulnerability in the NETCONF process of Cisco SD-WAN vEdge Routers could allow an authenticated, local attacker to cause an affected device to run out of memory, resulting in a denial of service (DoS) condition. This vulnerability is due to insufficient memory management when an affected device receives large amounts of traffic. An attacker could exploit this vulnerability by sending malicious traffic to an affected device. A successful exploit could allow the attacker to cause the device to crash, resulting in a DoS condition.

An issue was discovered in Xen through 4.14.x. Nodes in xenstore have an ownership. In oxenstored, a owner could give a node away. However, node ownership has quota implications. Any guest can run another guest out of quota, or create an unbounded number of nodes owned by dom0, thus running xenstored out of memory A malicious guest administrator can cause a denial of service against a specific guest or against the whole host. All systems using oxenstored are vulnerable. Building and using oxenstored is the default in the upstream Xen distribution, if the Ocaml compiler is available. Systems using C xenstored are not vulnerable.
