high Nessus Plugin ID 163729

Language:

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-2022:5821 advisory.

 - QEMU: QXL: integer overflow in cursor_alloc() can lead to heap buffer overflow (CVE-2021-4206)

 - QEMU: QXL: double fetch in qxl_cursor() can lead to heap buffer overflow (CVE-2021-4207)

 - QEMU: virtio-net: map leaking on error during receive (CVE-2022-26353)

 - QEMU: vhost-vsock: missing virtqueue detach on error can lead to memory leak (CVE-2022-26354)

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

Solution

Update the affected packages.
