Summary
[none]
Details

An issue was discovered in Xen 4.6 through 4.14.x. When acting upon a guest XSRESETWATCHES request, not all tracking information is freed. A guest can cause unbounded memory usage in oxenstored. This can lead to a system-wide DoS. Only systems using the Ocaml Xenstored implementation are vulnerable. Systems using the C Xenstored implementation are not vulnerable.
