"The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in
the openSUSE-SU-2021:3605-1 advisory.

  - An out-of-bounds write flaw was found in the UAS (USB Attached SCSI) device emulation of QEMU in versions
    prior to 6.2.0-rc0. The device uses the guest supplied stream number unchecked, which can lead to out-of-
    bounds access to the UASDevice->data3 and UASDevice->status3 fields. A malicious guest user could use this
    flaw to crash QEMU or potentially achieve code execution with the privileges of the QEMU process on the
    host. (CVE-2021-3713)

  - QEMU: virtio-net: heap use-after-free in virtio_net_receive_rcu (CVE-2021-3748)

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