Title:	Huawei EulerOS: Security Advisory for libvirt (EulerOS-SA-2024-2133)
Summary:	The remote host is missing an update for the Huawei EulerOS 'libvirt' package(s) announced via the EulerOS-SA-2024-2133 advisory.
Description:	Summary: The remote host is missing an update for the Huawei EulerOS 'libvirt' package(s) announced via the EulerOS-SA-2024-2133 advisory. Vulnerability Insight: 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) Affected Software/OS: 'libvirt' package(s) on Huawei EulerOS Virtualization release 2.10.0. Solution: Please install the updated package(s). CVSS Score: 4.9 CVSS Vector: AV:L/AC:L/Au:N/C:N/I:N/A:C
