"The version of qemu installed on the remote host is prior to 3.1.0-8. It is, therefore, affected by multiple
vulnerabilities as referenced in the ALAS2-2023-2169 advisory.

  - An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw
    exists in the bootp_input() function and could occur while processing a udp packet that is smaller than
    the size of the 'bootp_t' structure. A malicious guest could use this flaw to leak 10 bytes of
    uninitialized heap memory from the host. The highest threat from this vulnerability is to data
    confidentiality. This flaw affects libslirp versions prior to 4.6.0. (CVE-2021-3592)

  - An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw
    exists in the udp6_input() function and could occur while processing a udp packet that is smaller than the
    size of the 'udphdr' structure. This issue may lead to out-of-bounds read access or indirect host memory
    disclosure to the guest. The highest threat from this vulnerability is to data confidentiality. This flaw
    affects libslirp versions prior to 4.6.0. (CVE-2021-3593)
