RHEL 9 : libvirt (RHSA-2024:2560)

medium Nessus Plugin ID 194830

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for libvirt.

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:2560 advisory.

 The libvirt library contains a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. In addition, libvirt provides tools for remote management of virtualized systems.

 Security Fixes:

 * libvirt: off-by-one error in udevListInterfacesByStatus() (CVE-2024-1441)

 * 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.

 Bug Fixes:

 * libvirt: off-by-one error in udevListInterfacesByStatus() [rhel-9] (JIRA:RHEL-25081)

 * libvirt: negative g_new0 length can lead to unbounded memory allocation [rhel-9] (JIRA:RHEL-29515)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

Solution

Update the RHEL libvirt package based on the guidance in RHSA-2024:2560.
