DISPUTED The xdr_bytes and xdr_string functions in the GNU C Library
(aka glibc or libc6) 2.25 mishandle failures of buffer deserialization,
which allows remote attackers to cause a denial of service (virtual memory
allocation, or memory consumption if an overcommit setting is not used) via
a crafted UDP packet to port 111, a related issue to CVE-2017-8779. NOTE:
