Oracle Linux 9 : libvirt (ELSA-2022-8003)
Discription

The remote Oracle Linux 9 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2022-8003 advisory.

– A flaw was found in the libvirt nwfilter driver. The virNWFilterObjListNumOfNWFilters method failed to acquire the driver->nwfilters mutex before iterating over virNWFilterObj instances. There was no protection to stop another thread from concurrently modifying the driver->nwfilters object. This flaw allows a malicious, unprivileged user to exploit this issue via libvirt’s API virConnectNumOfNWFilters to crash the network filter management daemon (libvirtd/virtnwfilterd). (CVE-2022-0897)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.Read More
