"The remote SUSE Linux SLES11 host has a package installed that is affected by multiple vulnerabilities as referenced in
the SUSE-SU-2019:14151-1 advisory.

  - interface_release_resource in hw/display/qxl.c in QEMU 3.1.x through 4.0.0 has a NULL pointer dereference.
    (CVE-2019-12155)

  - qemu-bridge-helper.c in QEMU 3.1 and 4.0.0 does not ensure that a network interface name (obtained from
    bridge.conf or a --br=bridge option) is limited to the IFNAMSIZ size, which can lead to an ACL bypass.
    (CVE-2019-13164)

  - ip_reass in ip_input.c in libslirp 4.0.0 has a heap-based buffer overflow via a large packet because it
    mishandles a case involving the first fragment. (CVE-2019-14378)

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