NFS Server Resource Exhaustion Vulnerability

CVE-2018-17159 · HIGH Severity

AV:N/AC:L/AU:N/C:N/I:N/A:C

In FreeBSD before 11.2-STABLE(r340854) and 11.2-RELEASE-p5, the NFS server lacks a bounds check in the READDIRPLUS NFS request. Unprivileged remote users with access to the NFS server can cause a resource exhaustion by forcing the server to allocate an arbitrarily large memory allocation.
