CVE-2017-8779

Priority
Description
rpcbind through 0.2.4, LIBTIRPC through 1.0.1 and 1.0.2-rc through
1.0.2-rc3, and NTIRPC through 1.4.3 do not consider the maximum RPC data
size during memory allocation for XDR strings, which allows remote
attackers to cause a denial of service (memory consumption with no
subsequent free) via a crafted UDP packet to port 111, aka rpcbomb.

Notes
mdeslaurpatch used by Debian in 0.2.3-0.6 isn't the correct one and
the reproducer still works against rpcbind
