Scientific Linux Security Update : libtirpc on SL7.x x86_64

High Nessus Plugin ID 100347

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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)

Solution

Update the affected libtirpc, libtirpc-debuginfo and / or libtirpc-devel packages.
