EulerOS Virtualization 2.10.0 : libvirt (EulerOS-SA-2024-2133)

medium Nessus Plugin ID 205822

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

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

 A race condition leading to a stack use-after-free flaw was found in libvirt. Due to a bad assumption in the virNetClientIOEventLoop() method, the `data` pointer to a stack-allocated virNetClientIOEventData structure ended up being used in the virNetClientIOEventFD callback while the data pointer's stack frame was concurrently being 'freed' when returning from virNetClientIOEventLoop(). The 'virtproxyd' daemon can be used to trigger requests. If libvirt is configured with fine-grained access control, this issue, in theory, allows a user to escape their otherwise limited access. This flaw allows a local, unprivileged user to access virtproxyd without authenticating. Remote users would need to authenticate before they could access it.(CVE-2024-4418)

Tenable has extracted the preceding description block directly from the EulerOS Virtualization libvirt security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected libvirt packages.
