EulerOS Virtualization 2.9.1 : libtirpc (EulerOS-SA-2022-2353)

high Nessus Plugin ID 165402

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

According to the versions of the libtirpc package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

 - In libtirpc before 1.3.3rc1, remote attackers could exhaust the file descriptors of a process that uses libtirpc because idle TCP connections are mishandled. This can, in turn, lead to an svc_run infinite loop without accepting new connections. (CVE-2021-46828)

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 packages.
