RHEL 8 : virt:rhel and virt-devel:rhel (RHSA-2024:3253)

medium Nessus Plugin ID 197754

Language:

Synopsis

The remote Red Hat host is missing a security update for virt:rhel / virt-devel:rhel.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2024:3253 advisory.

 Kernel-based Virtual Machine (KVM) offers a full virtualization solution for Linux on numerous hardware platforms. The virt:rhel module contains packages which provide user-space components used to run virtual machines using KVM. The packages also provide APIs for managing and interacting with the virtualized systems.

 Security Fix(es):

 * libvirt: negative g_new0 length can lead to unbounded memory allocation (CVE-2024-2494)

 For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux 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 RHEL virt:rhel / virt-devel:rhel packages based on the guidance in RHSA-2024:3253.
