Red Hat Security Advisory 2017-1262-01 - The rpcbind utility is a server that converts Remote Procedure Call program numbers into universal addresses. It must be running on the host to be able to make RPC calls on a server on that machine. Security Fix: It was found that due to the way rpcbind uses libtirpc, a memory leak can occur when parsing specially crafted XDR messages. An attacker sending thousands of messages to rpcbind could cause its memory usage to grow without bound, eventually causing it to be terminated by the OOM killer.

Red Hat Security Advisory 2017-1267-01 - The rpcbind utility is a server that converts Remote Procedure Call program numbers into universal addresses.

Red Hat Security Advisory 2017-1268-01 - The libtirpc packages contain SunLib's implementation of transport-independent remote procedure call documentation, which includes a library required by programs in the nfs-utils and rpcbind packages. Security Fix: It was found that due to the way rpcbind uses libtirpc, a memory leak can occur when parsing specially crafted XDR messages. An attacker sending thousands of messages to rpcbind could cause its memory usage to grow without bound, eventually causing it to be terminated by the OOM killer.

Red Hat Security Advisory 2017-1395-01 - This package contains a new implementation of the original libtirpc, transport-independent RPC library for NFS-Ganesha. Security Fix: It was found that due to the way rpcbind uses libtirpc, a memory leak can occur when parsing specially crafted XDR messages. An attacker sending thousands of messages to rpcbind could cause its memory usage to grow without bound, eventually causing it to be terminated by the OOM killer.

Asterisk Project Security Advisory - A memory leak occurs when an Asterisk pjsip session object is created and that call gets rejected before the session itself is fully established. When this happens the session object never gets destroyed.
