    (CVE-2023-45237)

    EDK2 contains a vulnerability in the PeCoffLoaderRelocateImage(). An Attacker may cause memory corruption     due to an overflow via an adjacent network. A successful exploit of this vulnerability may lead to a loss     of Confidentiality, Integrity, and/or Availability. (CVE-2024-38796)

    Issue summary: Use of the low-level GF(2^m) elliptic curve APIs with untrustedexplicit values for the     field polynomial can lead to out-of-bounds memory readsor writes.

    Impact summary: Out of bound memory writes can lead to an application crash oreven a possibility of a     remote code execution, however, in all the protocolsinvolving Elliptic Curve Cryptography that we're aware     of, either only namedcurves are supported, or, if explicit curve parameters are supported, theyspecify     an X9.62 encoding of binary (GF(2^m)) curves that can't representproblematic input values. Thus the     likelihood of existence of a vulnerableapplication is low.

    In particular, the X9.62 encoding is used for ECC keys in X.509 certificates,so problematic inputs cannot     occur in the context of processing X.509certificates.  Any problematic use-cases would have to be using an     exoticcurve encoding.

    The affected APIs include: EC_GROUP_new_curve_GF2m(), EC_GROUP_new_from_params(),and various supporting     BN_GF2m_*() functions.

    Applications working with exotic explicit binary (GF(2^m)) curve parameters,that make it possible to     represent invalid field polynomials with a zeroconstant term, via the above or similar APIs, may terminate     abruptly as aresult of reading or writing outside of array bounds.  Remote code executioncannot easily be     ruled out.

    The FIPS modules in 3.3, 3.2, 3.1 and 3.0 are not affected by this issue. (CVE-2024-9143)

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)
