RHSA-2017:1263 - Important: libtirpc security update


Synopsis

Important: libtirpc security update

Type/Severity

Security Advisory Important

Topic

An update for libtirpc is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description

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)
