libtirpc: Multiple issues (4.1)
Last modified: 2019-04-11 19:24:32 CEST
Upstream Debian package version 0.2.2-5+deb7u1 fixes this issue: * rpcbind does 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. (CVE-2017-8779) libtirpc is a transport-independent RPC library used by rpcbind and other programs.
