EulerOS 2.0 SP1 : libtirpc (EulerOS-SA-2017-1096)

High Nessus Plugin ID 100689

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the version of the libtirpc package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

- 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected libtirpc package.
