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.

Affected configurations

• rpcbind project rpcbind (<= 0.2.4) • libtirpc project libtirpc (<= 1.0.1) • ntirpc project ntirpc (<= 1.4.3)
