Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:0648 advisory.

- QEMU: heap buffer overflow in iscsi_aio_ioctl_cb() in block/iscsi.c may lead to information disclosure (CVE-2020-11947)

- QEMU: assertion failure through usb_packet_unmap() in hw/usb/hcd-ehci.c (CVE-2020-25723)

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

Solution

Update the affected packages.
