Title:	RedHat Update for libtirpc RHSA-2017:1263-01
Summary:	The remote host is missing an update for the 'libtirpc'; package(s) announced via the referenced advisory.
Description:	Summary: The remote host is missing an update for the 'libtirpc' package(s) announced via the referenced advisory. Vulnerability Insight: The libtirpc packages contain SunLib's implementation of transport-independent remote procedure call (TI-RPC) documentation, which includes a library required by programs in the nfs-utils and rpcbind packages. Security Fix(es): * It was found that due to the way rpcbind uses libtirpc (libntirpc), 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. (CVE-2017-8779) Affected Software/OS: libtirpc on Red Hat Enterprise Linux Server (v. 7) Solution: Please Install the Updated Packages. CVSS Score: 7.8 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:C
