The version of OpenSSL installed on the remote host is prior to 3.2.1. It is, therefore, affected by multiple vulnerabilities as referenced in the 3.2.1 advisory.

  - Issue summary: Processing a maliciously formatted PKCS12 file may lead OpenSSL to crash leading to a     potential Denial of Service attack Impact summary: Applications loading files in the PKCS12 format from     untrusted sources might terminate abruptly. A file in PKCS12 format can contain certificates and keys and     may come from an untrusted source. The PKCS12 specification allows certain fields to be NULL, but OpenSSL     does not correctly check for this case. This can lead to a NULL pointer dereference that results in     OpenSSL crashing. If an application processes PKCS12 files from an untrusted source using the OpenSSL APIs     then that application will be vulnerable to this issue. OpenSSL APIs that are vulnerable to this are:
    PKCS12_parse(), PKCS12_unpack_p7data(), PKCS12_unpack_p7encdata(), PKCS12_unpack_authsafes() and     PKCS12_newpass(). We have also fixed a similar issue in SMIME_write_PKCS7(). However since this function     is related to writing data we do not consider it security significant. The FIPS modules in 3.2, 3.1 and     3.0 are not affected by this issue. (CVE-2024-0727)

  - Issue summary: Checking excessively long invalid RSA public keys may take a long time. Impact summary:
    Applications that use the function EVP_PKEY_public_check() to check RSA public keys may experience long     delays. Where the key that is being checked has been obtained from an untrusted source this may lead to a     Denial of Service. When function EVP_PKEY_public_check() is called on RSA public keys, a computation is     done to confirm that the RSA modulus, n, is composite. For valid RSA keys, n is a product of two or more     large primes and this computation completes quickly. However, if n is an overly large prime, then this     computation would take a long time. An application that calls EVP_PKEY_public_check() and supplies an RSA     key obtained from an untrusted source could be vulnerable to a Denial of Service attack. The function     EVP_PKEY_public_check() is not called from other OpenSSL functions however it is called from the OpenSSL     pkey command line application. For that reason that application is also vulnerable if used with the     '-pubin' and '-check' options on untrusted data. The OpenSSL SSL/TLS implementation is not affected by     this issue. The OpenSSL 3.0 and 3.1 FIPS providers are affected by this issue. (CVE-2023-6237)

  - Issue summary: The POLY1305 MAC (message authentication code) implementation contains a bug that might     corrupt the internal state of applications running on PowerPC CPU based platforms if the CPU provides     vector instructions. Impact summary: If an attacker can influence whether the POLY1305 MAC algorithm is     used, the application state might be corrupted with various application dependent consequences. The     POLY1305 MAC (message authentication code) implementation in OpenSSL for PowerPC CPUs restores the     contents of vector registers in a different order than they are saved. Thus the contents of some of these     vector registers are corrupted when returning to the caller. The vulnerable code is used only on newer     PowerPC processors supporting the PowerISA 2.07 instructions. The consequences of this kind of internal     application state corruption can be various - from no consequences, if the calling application does not     depend on the contents of non-volatile XMM registers at all, to the worst consequences, where the attacker     could get complete control of the application process. However unless the compiler uses the vector     registers for storing pointers, the most likely consequence, if any, would be an incorrect result of some     application dependent calculations or a crash leading to a denial of service. The POLY1305 MAC algorithm     is most frequently used as part of the CHACHA20-POLY1305 AEAD (authenticated encryption with associated     data) algorithm. The most common usage of this AEAD cipher is with TLS protocol versions 1.2 and 1.3. If     this cipher is enabled on the server a malicious client can influence whether this AEAD cipher is used.
    This implies that TLS server applications using OpenSSL can be potentially impacted. However we are     currently not aware of any concrete application that would be affected by this issue therefore we consider     this a Low severity security issue. (CVE-2023-6129)

  - Issue summary: Generating excessively long X9.42 DH keys or checking excessively long X9.42 DH keys or     parameters may be very slow. Impact summary: Applications that use the functions DH_generate_key() to     generate an X9.42 DH key may experience long delays. Likewise, applications that use DH_check_pub_key(),     DH_check_pub_key_ex() or EVP_PKEY_public_check() to check an X9.42 DH key or X9.42 DH parameters may     experience long delays. Where the key or parameters that are being checked have been obtained from an     untrusted source this may lead to a Denial of Service. While DH_check() performs all the necessary checks     (as of CVE-2023-3817), DH_check_pub_key() doesn't make any of these checks, and is therefore vulnerable     for excessively large P and Q parameters. Likewise, while DH_generate_key() performs a check for an     excessively large P, it doesn't check for an excessively large Q. An application that calls     DH_generate_key() or DH_check_pub_key() and supplies a key or parameters obtained from an untrusted source     could be vulnerable to a Denial of Service attack. DH_generate_key() and DH_check_pub_key() are also     called by a number of other OpenSSL functions. An application calling any of those other functions may     similarly be affected. The other functions affected by this are DH_check_pub_key_ex(),     EVP_PKEY_public_check(), and EVP_PKEY_generate(). Also vulnerable are the OpenSSL pkey command line     application when using the -pubcheck option, as well as the OpenSSL genpkey command line application.
    The OpenSSL SSL/TLS implementation is not affected by this issue. The OpenSSL 3.0 and 3.1 FIPS providers     are not affected by this issue. (CVE-2023-5678)

The remote NewStart CGSL host, running version MAIN 7.02, has openssl packages installed that are affected by multiple vulnerabilities:

  - Issue summary: A bug has been identified in the processing of key and initialisation vector (IV) lengths.
    This can lead to potential truncation or overruns during the initialisation of some symmetric ciphers.
    Impact summary: A truncation in the IV can result in non-uniqueness, which could result in loss of     confidentiality for some cipher modes. When calling EVP_EncryptInit_ex2(), EVP_DecryptInit_ex2() or     EVP_CipherInit_ex2() the provided OSSL_PARAM array is processed after the key and IV have been     established. Any alterations to the key length, via the keylen parameter or the IV length, via the     ivlen parameter, within the OSSL_PARAM array will not take effect as intended, potentially causing     truncation or overreading of these values. The following ciphers and cipher modes are impacted: RC2, RC4,     RC5, CCM, GCM and OCB. For the CCM, GCM and OCB cipher modes, truncation of the IV can result in loss of     confidentiality. For example, when following NIST's SP 800-38D section 8.2.1 guidance for constructing a     deterministic IV for AES in GCM mode, truncation of the counter portion could lead to IV reuse. Both     truncations and overruns of the key and overruns of the IV will produce incorrect results and could, in     some cases, trigger a memory exception. However, these issues are not currently assessed as security     critical. Changing the key and/or IV lengths is not considered to be a common operation and the vulnerable     API was recently introduced. Furthermore it is likely that application developers will have spotted this     problem during testing since decryption would fail unless both peers in the communication were similarly     vulnerable. For these reasons we expect the probability of an application being vulnerable to this to be     quite low. However if an application is vulnerable then this issue is considered very serious. For these     reasons we have assessed this issue as Moderate severity overall. The OpenSSL SSL/TLS implementation is     not affected by this issue. The OpenSSL 3.0 and 3.1 FIPS providers are not affected by this because the     issue lies outside of the FIPS provider boundary. OpenSSL 3.1 and 3.0 are vulnerable to this issue.
    (CVE-2023-5363)

  - Issue summary: Checking excessively long DH keys or parameters may be very slow. Impact summary:
    Applications that use the functions DH_check(), DH_check_ex() or EVP_PKEY_param_check() to check a DH key     or DH parameters may experience long delays. Where the key or parameters that are being checked have been     obtained from an untrusted source this may lead to a Denial of Service. The function DH_check() performs     various checks on DH parameters. One of those checks confirms that the modulus ('p' parameter) is not too     large. Trying to use a very large modulus is slow and OpenSSL will not normally use a modulus which is     over 10,000 bits in length. However the DH_check() function checks numerous aspects of the key or     parameters that have been supplied. Some of those checks use the supplied modulus value even if it has     already been found to be too large. An application that calls DH_check() and supplies a key or parameters     obtained from an untrusted source could be vulernable to a Denial of Service attack. The function     DH_check() is itself called by a number of other OpenSSL functions. An application calling any of those     other functions may similarly be affected. The other functions affected by this are DH_check_ex() and     EVP_PKEY_param_check(). Also vulnerable are the OpenSSL dhparam and pkeyparam command line applications     when using the '-check' option. The OpenSSL SSL/TLS implementation is not affected by this issue. The     OpenSSL 3.0 and 3.1 FIPS providers are not affected by this issue. (CVE-2023-3446)
