Several vulnerabilities were discovered in openafs, an implementation of

project identifies the following problems:

CVE-2018-16947

Jeffrey Altman reported that the backup tape controller (butc)
process does accept incoming RPCs but does not require (or allow
for) authentication of those RPCs, allowing an unauthenticated
attacker to perform volume operations with administrator
credentials.

CVE-2018-16948

Mark Vitale reported that several RPC server routines do not fully
initialize output variables, leaking memory contents (from both
the stack and the heap) to the remote caller for
otherwise-successful RPCs.

CVE-2018-16949

Mark Vitale reported that an unauthenticated attacker can consume
large amounts of server memory and network bandwidth via
specially crafted requests, resulting in denial of service to
legitimate clients.
