F5 Networks BIG-IP : QEMU vulnerability (SOL16620) (Venom)

high Nessus Plugin ID 83749
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

An out-of-bounds memory access flaw, also known as 'VENOM,' was found in the way QEMU's virtual Floppy Disk Controller (FDC) handled FIFO buffer access while processing certain FDC commands. A privileged guest user could use this flaw to crash the guest or, potentially, execute arbitrary code on the host with the privileges of the host's QEMU process corresponding to the guest.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution SOL16620.
