EulerOS Virtualization 3.0.6.6 : iproute (EulerOS-SA-2022-2507)

medium Nessus Plugin ID 165913

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

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

 - iproute2 before 5.1.0 has a use-after-free in get_netnsid_from_name in ip/ipnetns.c. NOTE: security relevance may be limited to certain uses of setuid that, although not a default, are sometimes a configuration option offered to end users. Even when setuid is used, other factors (such as C library configuration) may block exploitability. (CVE-2019-20795)

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 iproute packages.
