CBL Mariner 2.0 Security Update: libvirt (CVE-2024-2496)

medium Nessus Plugin ID 201254

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of libvirt installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-2496 advisory.

 - A NULL pointer dereference flaw was found in the udevConnectListAllInterfaces() function in libvirt. This issue can occur when detaching a host interface while at the same time collecting the list of interfaces via virConnectListAllInterfaces API. This flaw could be used to perform a denial of service attack by causing the libvirt daemon to crash. (CVE-2024-2496)

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 packages.
