Linux Distros Unpatched Vulnerability : CVE-2019-3886

medium Nessus Plugin ID 222935

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - An incorrect permissions check was discovered in libvirt 4.8.0 and above. The readonly permission was allowed to invoke APIs depending on the guest agent, which could lead to potentially disclosing unintended information or denial of service by causing libvirt to block. (CVE-2019-3886)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
