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 read/write access flaw was found in the USB emulator of the QEMU in versions before 5.2.0. This issue occurs while processing USB packets from a guest when USBDevice 'setup_len' exceeds its 'data_buf[4096]' in the do_token_in, do_token_out routines. This flaw allows a guest user to crash the QEMU process, resulting in a denial of service, or the potential execution of arbitrary code with the privileges of the QEMU process on the host. (CVE-2020-14364)

Impact

A local attacker may be able to cause a denial of service (DoS) or execute arbitrary code on the host.This issue affects all BIG-IPplatforms that support Virtual Clustered Multiprocessing (vCMP).

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K09081535.
