In libtirpc before 1.3.3rc1, remote attackers could exhaust the file
descriptors of a process that uses libtirpc because idle TCP connections
are mishandled. This can, in turn, lead to an svc_run infinite loop without
accepting new connections.

Notes

Author Note
alexmurray ntirpc is forked from libtirpc so shares a lot of code
