Vulnerabilities description

  • CVE-2022-36763

    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-2022-36764

    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-2022-36765

    A flaw was found in the CreateHob() function in EDK2. An attacker, leveraging a local network, can initiate an integer overflow leading to a buffer overflow. This issue arises during size alignment within the CreateHob() function, requiring activation in the PEI phase. Successful exploitation of this flaw poses a moderate threat to confidentiality and integrity, however, the primary consequence is likely a crash or denial of service.

  • CVE-2023-45229

    EDK2's Network Package is susceptible to an out-of-bounds read vulnerability when processing the IA_NA or IA_TA option in a DHCPv6 Advertise 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 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-2023-45232

    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-2023-45233

    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-2023-45235

    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.
