Fedora 38 : libvirt (2024-2d35e47af3)

medium Nessus Plugin ID 190390

Language:

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 38 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2024-2d35e47af3 advisory.

 - A vulnerability was found in libvirt. This security flaw ouccers due to repeatedly querying an SR-IOV PCI device's capabilities that exposes a memory leak caused by a failure to free the virPCIVirtualFunction array within the parent struct's g_autoptr cleanup. (CVE-2023-2700)

 - A flaw was found in libvirt. The virStoragePoolObjListSearch function does not return a locked pool as expected, resulting in a race condition and denial of service when attempting to lock the same object from another thread. This issue could allow clients connecting to the read-only socket to crash the libvirt daemon. (CVE-2023-3750)

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 affected libvirt package.
