CBL Mariner 2.0 Security Update: libvirt (CVE-2024-2494)

medium Nessus Plugin ID 201812

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-2024-2494 advisory.

 - A flaw was found in the RPC library APIs of libvirt. The RPC server deserialization code allocates memory for arrays before the non-negative length check is performed by the C API entry points. Passing a negative length to the g_new0 function results in a crash due to the negative length being treated as a huge positive number. This flaw allows a local, unprivileged user to perform a denial of service attack by causing the libvirt daemon to crash. (CVE-2024-2494)

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.
