The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:1790-1 advisory.

    - CVE-2023-0464: Fixed excessive Resource Usage Verifying X.509 Policy Constraints (bsc#1209624).
    - CVE-2023-0465: Invalid certificate policies in leaf certificates were silently ignored (bsc#1209878).
    - CVE-2023-0466: Certificate policy check were not enabled (bsc#1209873).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of OpenSSL installed on the remote host is prior to 3.1.1. It is, therefore, affected by multiple vulnerabilities as referenced in the 3.1.1 advisory.

  - Issue summary: Processing some specially crafted ASN.1 object identifiers or data containing them may be     very slow. Impact summary: Applications that use OBJ_obj2txt() directly, or use any of the OpenSSL     subsystems OCSP, PKCS7/SMIME, CMS, CMP/CRMF or TS with no message size limit may experience notable to     very long delays when processing those messages, which may lead to a Denial of Service. An OBJECT     IDENTIFIER is composed of a series of numbers - sub-identifiers - most of which have no size limit.
    OBJ_obj2txt() may be used to translate an ASN.1 OBJECT IDENTIFIER given in DER encoding form (using the     OpenSSL type ASN1_OBJECT) to its canonical numeric text form, which are the sub-identifiers of the OBJECT     IDENTIFIER in decimal form, separated by periods. When one of the sub-identifiers in the OBJECT IDENTIFIER     is very large (these are sizes that are seen as absurdly large, taking up tens or hundreds of KiBs), the     translation to a decimal number in text may take a very long time. The time complexity is O(n^2) with 'n'     being the size of the sub-identifiers in bytes (*). With OpenSSL 3.0, support to fetch cryptographic     algorithms using names / identifiers in string form was introduced. This includes using OBJECT IDENTIFIERs     in canonical numeric text form as identifiers for fetching algorithms. Such OBJECT IDENTIFIERs may be     received through the ASN.1 structure AlgorithmIdentifier, which is commonly used in multiple protocols to     specify what cryptographic algorithm should be used to sign or verify, encrypt or decrypt, or digest     passed data. Applications that call OBJ_obj2txt() directly with untrusted data are affected, with any     version of OpenSSL. If the use is for the mere purpose of display, the severity is considered low. In     OpenSSL 3.0 and newer, this affects the subsystems OCSP, PKCS7/SMIME, CMS, CMP/CRMF or TS. It also impacts     anything that processes X.509 certificates, including simple things like verifying its signature. The     impact on TLS is relatively low, because all versions of OpenSSL have a 100KiB limit on the peer's     certificate chain. Additionally, this only impacts clients, or servers that have explicitly enabled client     authentication. In OpenSSL 1.1.1 and 1.0.2, this only affects displaying diverse objects, such as X.509     certificates. This is assumed to not happen in such a way that it would cause a Denial of Service, so     these versions are considered not affected by this issue in such a way that it would be cause for concern,     and the severity is therefore considered low. (CVE-2023-2650)

  - Applications that use a non-default option when verifying certificates may be vulnerable to an attack from     a malicious CA to circumvent certain checks. Invalid certificate policies in leaf certificates are     silently ignored by OpenSSL and other certificate policy checks are skipped for that certificate. A     malicious CA could use this to deliberately assert invalid certificate policies in order to circumvent     policy checking on the certificate altogether. Policy processing is disabled by default but can be enabled     by passing the `-policy' argument to the command line utilities or by calling the     `X509_VERIFY_PARAM_set1_policies()' function. (CVE-2023-0465)

  - Issue summary: The AES-XTS cipher decryption implementation for 64 bit ARM platform contains a bug that     could cause it to read past the input buffer, leading to a crash. Impact summary: Applications that use     the AES-XTS algorithm on the 64 bit ARM platform can crash in rare circumstances. The AES-XTS algorithm is     usually used for disk encryption. The AES-XTS cipher decryption implementation for 64 bit ARM platform     will read past the end of the ciphertext buffer if the ciphertext size is 4 mod 5 in 16 byte blocks, e.g.
    144 bytes or 1024 bytes. If the memory after the ciphertext buffer is unmapped, this will trigger a crash     which results in a denial of service. If an attacker can control the size and location of the ciphertext     buffer being decrypted by an application using AES-XTS on 64 bit ARM, the application is affected. This is     fairly unlikely making this issue a Low severity one. (CVE-2023-1255)

  - The function X509_VERIFY_PARAM_add0_policy() is documented to implicitly enable the certificate policy     check when doing certificate verification. However the implementation of the function does not enable the     check which allows certificates with invalid or incorrect policies to pass the certificate verification.
    As suddenly enabling the policy check could break existing deployments it was decided to keep the existing     behavior of the X509_VERIFY_PARAM_add0_policy() function. Instead the applications that require OpenSSL to     perform certificate policy check need to use X509_VERIFY_PARAM_set1_policies() or explicitly enable the     policy check by calling X509_VERIFY_PARAM_set_flags() with the X509_V_FLAG_POLICY_CHECK flag argument.
    Certificate policy checks are disabled by default in OpenSSL and are not commonly used by applications.
    (CVE-2023-0466)

  - A security vulnerability has been identified in all supported versions of OpenSSL related to the     verification of X.509 certificate chains that include policy constraints. Attackers may be able to exploit     this vulnerability by creating a malicious certificate chain that triggers exponential use of     computational resources, leading to a denial-of-service (DoS) attack on affected systems. Policy     processing is disabled by default but can be enabled by passing the `-policy' argument to the command line     utilities or by calling the `X509_VERIFY_PARAM_set1_policies()' function.

The version of Tencent Linux installed on the remote TencentOS Server 2 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0549 advisory.

    Package updates are available for TencentOS Server 2 that fix the following vulnerabilities:

    CVE-2022-1292:
    The c_rehash script does not properly sanitise shell metacharacters to prevent command injection. This     script is distributed by some operating systems in a manner where it is automatically executed. On such     operating systems, an attacker could execute arbitrary commands with the privileges of the script. Use of     the c_rehash script is considered obsolete and should be replaced by the OpenSSL rehash command line tool.
    Fixed in OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2). Fixed in OpenSSL 1.1.1o (Affected 1.1.1-1.1.1n).
    Fixed in OpenSSL 1.0.2ze (Affected 1.0.2-1.0.2zd).

    CVE-2022-2068:
    In addition to the c_rehash shell command injection identified in CVE-2022-1292, further circumstances     where the c_rehash script does not properly sanitise shell metacharacters to prevent command injection     were found by code review. When the CVE-2022-1292 was fixed it was not discovered that there are other     places in the script where the file names of certificates being hashed were possibly passed to a command     executed through the shell. This script is distributed by some operating systems in a manner where it is     automatically executed. On such operating systems, an attacker could execute arbitrary commands with the     privileges of the script. Use of the c_rehash script is considered obsolete and should be replaced by the     OpenSSL rehash command line tool. Fixed in OpenSSL 3.0.4 (Affected 3.0.0,3.0.1,3.0.2,3.0.3). Fixed in     OpenSSL 1.1.1p (Affected 1.1.1-1.1.1o). Fixed in OpenSSL 1.0.2zf (Affected 1.0.2-1.0.2ze).

    CVE-2023-0215:
    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-2023-0464:
    A security vulnerability has been identified in all supported versions

    of OpenSSL related to the verification of X.509 certificate chains     that include policy constraints.  Attackers may be able to exploit this     vulnerability by creating a malicious certificate chain that triggers     exponential use of computational resources, leading to a denial-of-service     (DoS) attack on affected systems.

    Policy processing is disabled by default but can be enabled by passing     the `-policy/' argument to the command line utilities or by calling the     `X509_VERIFY_PARAM_set1_policies()/' function.
