"According to the versions of the edk2 package installed, the EulerOS Virtualization installation on the remote host is
affected by the following vulnerabilities :

    EDK2 is susceptible to a vulnerability in the Tcg2MeasureGptTable() function, allowing a user to trigger a
    heap buffer overflow via a local network. Successful exploitation of this vulnerability may result in a
    compromise of confidentiality, integrity, and/or availability.(CVE-2022-36763)

    EDK2 is susceptible to a vulnerability in the Tcg2MeasurePeImage() function, allowing a user to trigger a
    heap buffer overflow via a local network. Successful exploitation of this vulnerability may result in a
    compromise of confidentiality, integrity, and/or availability.(CVE-2022-36764)

    EDK2 is susceptible to a vulnerability in the CreateHob() function, allowing a user to trigger a integer
    overflow to buffer overflow via a local network. Successful exploitation of this vulnerability may result
    in a compromise of confidentiality, integrity, and/or availability.(CVE-2022-36765)

    EDK2's Network Package is susceptible to a buffer overflow vulnerability via a long server ID option in
    DHCPv6 client. This vulnerability can be exploited by an attacker to gain unauthorized access and
    potentially lead to a loss of Confidentiality, Integrity and/or Availability.(CVE-2023-45230)

    EDK2's Network Package is susceptible to an out-of-bounds read vulnerability when processing  Neighbor
    Discovery Redirect message. This vulnerability can be exploited by an attacker to gain unauthorized access
    and potentially lead to a loss of Confidentiality.(CVE-2023-45231)

    EDK2's Network Package is susceptible to an infinite loop vulnerability when parsing unknown options in
    the Destination Options header of IPv6. This vulnerability can be exploited by an attacker to gain
    unauthorized access and potentially lead to a loss of Availability.(CVE-2023-45232)

    EDK2's Network Package is susceptible to an infinite lop vulnerability when parsing a PadN option in the
    Destination Options header of IPv6. This vulnerability can be exploited by an attacker to gain
    unauthorized access and potentially lead to a loss of Availability.(CVE-2023-45233)

    EDK2's Network Package is susceptible to a buffer overflow vulnerability when processing DNS Servers
    option from a DHCPv6 Advertise message. This vulnerability can be exploited by an attacker to gain
    unauthorized access and potentially lead to a loss of Confidentiality, Integrity and/or
    Availability.(CVE-2023-45234)

    EDK2's Network Package is susceptible to a buffer overflow vulnerability when handling Server ID option
    from a DHCPv6 proxy Advertise message. This vulnerability can be exploited by an attacker to gain
    unauthorized access and potentially lead to a loss of Confidentiality, Integrity and/or
    Availability.(CVE-2023-45235)
