According to the versions of the edk2 package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :
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)
EDK2's Network Package is susceptible to a predictable TCP Initial Sequence Number. This vulnerability can be exploited by an attacker to gain unauthorized access and potentially lead to a loss of Confidentiality.(CVE-2023-45234)
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-2023-45229)
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 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 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 a predictable TCP Initial Sequence Number. This vulnerability can be exploited by an attacker to gain unauthorized access and potentially lead to a loss of Confidentiality.(CVE-2023-45236)
EDK2's Network Package is susceptible to a predictable TCP Initial Sequence Number. This vulnerability can be exploited by an attacker to gain unauthorized access and potentially lead to a loss of Confidentiality.(CVE-2023-45237)
Tenable has extracted the preceding description block directly from the EulerOS Virtualization edk2 security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
