Insufficient input validation in MdeModulePkg in EDKII may allow an unauthenticated user to potentially enable escalation of privilege, denial of service and/or information disclosure via physical access.

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

  - Insufficient input validation in MdeModulePkg in EDKII may allow an unauthenticated user to potentially     enable escalation of privilege, denial of service and/or information disclosure via physical access.
    (CVE-2019-11098)

  - Existing CommBuffer checks in SmmEntryPoint will not catch underflow when computing BufferSize.
    (CVE-2021-38578)

  - The function PEM_read_bio_ex() reads a PEM file from a BIO and parses and decodes the 'name' (e.g.
    'CERTIFICATE'), any header data and the payload data. If the function succeeds then the 'name_out',     'header' and 'data' arguments are populated with pointers to buffers containing the relevant decoded data.
    The caller is responsible for freeing those buffers. It is possible to construct a PEM file that results     in 0 bytes of payload data. In this case PEM_read_bio_ex() will return a failure code but will populate     the header argument with a pointer to a buffer that has already been freed. If the caller also frees this     buffer then a double free will occur. This will most likely lead to a crash. This could be exploited by an     attacker who has the ability to supply malicious PEM files for parsing to achieve a denial of service     attack. The functions PEM_read_bio() and PEM_read() are simple wrappers around PEM_read_bio_ex() and     therefore these functions are also directly affected. These functions are also called indirectly by a     number of other OpenSSL functions including PEM_X509_INFO_read_bio_ex() and SSL_CTX_use_serverinfo_file()     which are also vulnerable. Some OpenSSL internal uses of these functions are not vulnerable because the     caller does not free the header argument if PEM_read_bio_ex() returns a failure code. These locations     include the PEM_read_bio_TYPE() functions as well as the decoders introduced in OpenSSL 3.0. The OpenSSL     asn1parse command line application is also impacted by this issue. (CVE-2022-4450)

  - The public API function BIO_new_NDEF is a helper function used for streaming ASN.1 data via a BIO. It is     primarily used internally to OpenSSL to support the SMIME, CMS and PKCS7 streaming capabilities, but may     also be called directly by end user applications. The function receives a BIO from the caller, prepends a     new BIO_f_asn1 filter BIO onto the front of it to form a BIO chain, and then returns the new head of the     BIO chain to the caller. Under certain conditions, for example if a CMS recipient public key is invalid,     the new filter BIO is freed and the function returns a NULL result indicating a failure. However, in this     case, the BIO chain is not properly cleaned up and the BIO passed by the caller still retains internal     pointers to the previously freed filter BIO. If the caller then goes on to call BIO_pop() on the BIO then     a use-after-free will occur. This will most likely result in a crash. This scenario occurs directly in the     internal function B64_write_ASN1() which may cause BIO_new_NDEF() to be called and will subsequently call     BIO_pop() on the BIO. This internal function is in turn called by the public API functions     PEM_write_bio_ASN1_stream, PEM_write_bio_CMS_stream, PEM_write_bio_PKCS7_stream, SMIME_write_ASN1,     SMIME_write_CMS and SMIME_write_PKCS7. Other public API functions that may be impacted by this include     i2d_ASN1_bio_stream, BIO_new_CMS, BIO_new_PKCS7, i2d_CMS_bio_stream and i2d_PKCS7_bio_stream. The OpenSSL     cms and smime command line applications are similarly affected. (CVE-2023-0215)

  - There is a type confusion vulnerability relating to X.400 address processing inside an X.509 GeneralName.
    X.400 addresses were parsed as an ASN1_STRING but the public structure definition for GENERAL_NAME     incorrectly specified the type of the x400Address field as ASN1_TYPE. This field is subsequently     interpreted by the OpenSSL function GENERAL_NAME_cmp as an ASN1_TYPE rather than an ASN1_STRING. When CRL     checking is enabled (i.e. the application sets the X509_V_FLAG_CRL_CHECK flag), this vulnerability may     allow an attacker to pass arbitrary pointers to a memcmp call, enabling them to read memory contents or     enact a denial of service. In most cases, the attack requires the attacker to provide both the certificate     chain and CRL, neither of which need to have a valid signature. If the attacker only controls one of these     inputs, the other input must already contain an X.400 address as a CRL distribution point, which is     uncommon. As such, this vulnerability is most likely to only affect applications which have implemented     their own functionality for retrieving CRLs over a network. (CVE-2023-0286)

    (CVE-2019-11098)

  - ASN.1 strings are represented internally within OpenSSL as an ASN1_STRING structure which contains a     buffer holding the string data and a field holding the buffer length. This contrasts with normal C strings     which are repesented as a buffer for the string data which is terminated with a NUL (0) byte. Although not     a strict requirement, ASN.1 strings that are parsed using OpenSSL's own d2i functions (and other similar     parsing functions) as well as any string whose value has been set with the ASN1_STRING_set() function will     additionally NUL terminate the byte array in the ASN1_STRING structure. However, it is possible for     applications to directly construct valid ASN1_STRING structures which do not NUL terminate the byte array     by directly setting the data and length fields in the ASN1_STRING array. This can also happen by using     the ASN1_STRING_set0() function. Numerous OpenSSL functions that print ASN.1 data have been found to     assume that the ASN1_STRING byte array will be NUL terminated, even though this is not guaranteed for     strings that have been directly constructed. Where an application requests an ASN.1 structure to be     printed, and where that ASN.1 structure contains ASN1_STRINGs that have been directly constructed by the     application without NUL terminating the data field, then a read buffer overrun can occur. The same thing     can also occur during name constraints processing of certificates (for example if a certificate has been     directly constructed by the application instead of loading it via the OpenSSL parsing functions, and the     certificate contains non NUL terminated ASN1_STRING structures). It can also occur in the     X509_get1_email(), X509_REQ_get1_email() and X509_get1_ocsp() functions. If a malicious actor can cause an     application to directly construct an ASN1_STRING and then process it through one of the affected OpenSSL     functions then this issue could be hit. This might result in a crash (causing a Denial of Service attack).
    It could also result in the disclosure of private memory contents (such as private keys, or sensitive     plaintext). Fixed in OpenSSL 1.1.1l (Affected 1.1.1-1.1.1k). Fixed in OpenSSL 1.0.2za (Affected     1.0.2-1.0.2y). (CVE-2021-3712)

  - Calls to EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate may overflow the output length argument     in some cases where the input length is close to the maximum permissable length for an integer on the     platform. In such cases the return value from the function call will be 1 (indicating success), but the     output length value will be negative. This could cause applications to behave incorrectly or crash.
    OpenSSL versions 1.1.1i and below are affected by this issue. Users of these versions should upgrade to     OpenSSL 1.1.1j. OpenSSL versions 1.0.2x and below are affected by this issue. However OpenSSL 1.0.2 is out     of support and no longer receiving public updates. Premium support customers of OpenSSL 1.0.2 should     upgrade to 1.0.2y. Other users should upgrade to 1.1.1j. Fixed in OpenSSL 1.1.1j (Affected 1.1.1-1.1.1i).
    Fixed in OpenSSL 1.0.2y (Affected 1.0.2-1.0.2x). (CVE-2021-23840)

It is possible     to construct an asn1 blob that successfully decodes and     have d2i_PKCS7() return a valid pointer and have     PKCS7_type_is_signed() also return success but have     Pkcs7->d.sign be a NULL     pointer.(CVE-2019-14584)IA32_FEATURE_CONTROL stays     unlocked in S3 after a warm reset(CVE-2019-14588)We     have found a TOCTOU vulnerability which allows an     attacker with physical access to achieve code execution     after the Boot Guard ACM computes and validates the     hash of the IBB and measured the firmware into the TPM     PCR0. This means the firmware will be marked as valid     and have normal PCR0 values even though unsigned code     has run. The root cause is when the FSP has finished     memory init and disables MTRRs (and thereby the cache)     in order to switch off No Evict Mode. The code doing     this (the SecCore PeiTemporaryRamDonePpi callback), is     executed directly from SPI flash, allowing an attacker     to intercept execution flow.
