According to the versions of the openssl packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    Issue summary: Applications using RSASVE key encapsulation to establish_x000D_     a secret encryption key can send contents of an uninitialized memory buffer to_x000D_     a malicious peer._x000D_
    _x000D_     Impact summary: The uninitialized buffer might contain sensitive data from the_x000D_     previous execution of the application process which leads to sensitive data_x000D_     leakage to an attacker._x000D_
    _x000D_     RSA_public_encrypt() returns the number of bytes written on success and -1_x000D_     on error. The affected code tests only whether the return value is non-zero._x000D_     As a result, if RSA encryption fails, encapsulation can still return success to_x000D_     the caller, set the output lengths, and leave the caller to use the contents of_x000D_     the ciphertext buffer as if a valid KEM ciphertext had been produced._x000D_
    _x000D_     If applications use EVP_PKEY_encapsulate() with RSA/RSASVE on an_x000D_     attacker-supplied invalid RSA public key without first validating that key,_x000D_     then this may cause stale or uninitialized contents of the caller-provided_x000D_     ciphertext buffer to be disclosed to the attacker in place of the KEM_x000D_     ciphertext._x000D_
    _x000D_     As a workaround calling EVP_PKEY_public_check() or_x000D_     EVP_PKEY_public_check_quick() before EVP_PKEY_encapsulate() will mitigate_x000D_     the issue._x000D_
    _x000D_     The FIPS modules in 3.6, 3.5, 3.4, 3.3, 3.1 and 3.0 are affected by this issue.(CVE-2026-31790)

    Issue summary: An uncommon configuration of clients performing DANE TLSA-based_x000D_     server authentication, when paired with uncommon server DANE TLSA records, may_x000D_     result in a use-after-free and/or double-free on the client side._x000D_
    _x000D_     Impact summary: A use after free can have a range of potential consequences_x000D_     such as the corruption of valid data, crashes or execution of arbitrary code._x000D_
    _x000D_     However, the issue only affects clients that make use of TLSA records with both_x000D_     the PKIX-TA(0/PKIX-EE(1) certificate usages and the DANE-TA(2) certificate_x000D_     usage._x000D_
    _x000D_     By far the most common deployment of DANE is in SMTP MTAs for which RFC7672_x000D_     recommends that clients treat as 'unusable' any TLSA records that have the PKIX_x000D_     certificate usages.  These SMTP (or other similar) clients are not vulnerable_x000D_     to this issue.  Conversely, any clients that support only the PKIX usages, and_x000D_     ignore the DANE-TA(2) usage are also not vulnerable._x000D_
    _x000D_     The client would also need to be communicating with a server that publishes a_x000D_     TLSA RRset with both types of TLSA records._x000D_
    _x000D_     No FIPS modules are affected by this issue, the problem code is outside the_x000D_     FIPS module boundary.(CVE-2026-28387)

    Issue summary: When a delta CRL that contains a Delta CRL Indicator extension_x000D_     is processed a NULL pointer dereference might happen if the required CRL_x000D_     Number extension is missing._x000D_
    _x000D_     Impact summary: A NULL pointer dereference can trigger a crash which_x000D_     leads to a Denial of Service for an application._x000D_
    _x000D_     When CRL processing and delta CRL processing is enabled during X.509_x000D_     certificate verification, the delta CRL processing does not check_x000D_     whether the CRL Number extension is NULL before dereferencing it._x000D_     When a malformed delta CRL file is being processed, this parameter_x000D_     can be NULL, causing a NULL pointer dereference._x000D_
    _x000D_     Exploiting this issue requires the X509_V_FLAG_USE_DELTAS flag to be enabled in_x000D_     the verification context, the certificate being verified to contain a_x000D_     freshestCRL extension or the base CRL to have the EXFLAG_FRESHEST flag set, and_x000D_     an attacker to provide a malformed CRL to an application that processes it._x000D_
    _x000D_     The vulnerability is limited to Denial of Service and cannot be escalated to_x000D_     achieve code execution or memory disclosure. For that reason the issue was_x000D_     assessed as Low severity according to our Security Policy._x000D_
    _x000D_     The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by this issue,_x000D_     as the affected code is outside the OpenSSL FIPS module boundary.(CVE-2026-28388)

    Issue summary: Converting an excessively large OCTET STRING value to_x000D_     a hexadecimal string leads to a heap buffer overflow on 32 bit platforms._x000D_
    _x000D_     Impact summary: A heap buffer overflow may lead to a crash or possibly_x000D_     an attacker controlled code execution or other undefined behavior._x000D_
    _x000D_     If an attacker can supply a crafted X.509 certificate with an excessively_x000D_     large OCTET STRING value in extensions such as the Subject Key Identifier_x000D_     (SKID) or Authority Key Identifier (AKID) which are being converted to hex,_x000D_     the size of the buffer needed for the result is calculated as multiplication_x000D_     of the input length by 3. On 32 bit platforms, this multiplication may overflow_x000D_     resulting in the allocation of a smaller buffer and a heap buffer overflow._x000D_
    _x000D_     Applications and services that print or log contents of untrusted X.509_x000D_     certificates are vulnerable to this issue. As the certificates would have_x000D_     to have sizes of over 1 Gigabyte, printing or logging such certificates_x000D_     is a fairly unlikely operation and only 32 bit platforms are affected,_x000D_     this issue was assigned Low severity._x000D_
    _x000D_     The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by this_x000D_     issue, as the affected code is outside the OpenSSL FIPS module boundary.(CVE-2026-31789)

    Issue summary: During processing of a crafted CMS EnvelopedData message_x000D_     with KeyAgreeRecipientInfo a NULL pointer dereference can happen._x000D_
    _x000D_     Impact summary: Applications that process attacker-controlled CMS data may_x000D_     crash before authentication or cryptographic operations occur resulting in_x000D_     Denial of Service._x000D_
    _x000D_     When a CMS EnvelopedData message that uses KeyAgreeRecipientInfo is_x000D_     processed, the optional parameters field of KeyEncryptionAlgorithmIdentifier_x000D_     is examined without checking for its presence. This results in a NULL_x000D_     pointer dereference if the field is missing._x000D_
    _x000D_     Applications and services that call CMS_decrypt() on untrusted input_x000D_     (e.g., S/MIME processing or CMS-based protocols) are vulnerable._x000D_
    _x000D_     The FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by this_x000D_     issue, as the affected code is outside the OpenSSL FIPS module boundary.(CVE-2026-28389)

    Issue summary: During processing of a crafted CMS EnvelopedData message_x000D_     with KeyTransportRecipientInfo a NULL pointer dereference can happen._x000D_
    _x000D_     Impact summary: Applications that process attacker-controlled CMS data may_x000D_     crash before authentication or cryptographic operations occur resulting in_x000D_     Denial of Service._x000D_
    _x000D_     When a CMS EnvelopedData message that uses KeyTransportRecipientInfo with_x000D_     RSA-OAEP encryption is processed, the optional parameters field of_x000D_     RSA-OAEP SourceFunc algorithm identifier is examined without checking_x000D_     for its presence. This results in a NULL pointer dereference if the field_x000D_     is missing._x000D_

The version of AOS installed on the remote host is prior to 7.6.0.6. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-7.6.0.6 advisory.

  - In an untrusted JMS environment, org.springframework.jms.support.converter.MappingJackson2MessageConverter     and org.springframework.jms.support.converter.JacksonJsonMessageConverter allow arbitrary class     instantiation, which can lead to unauthorized actions via gadget class deserialization. Affected versions:
    Spring Framework 7.0.0 through 7.0.7; 6.2.0 through 6.2.18; 6.1.0 through 6.1.27; 5.3.0 through 5.3.48.
    (CVE-2026-41855)

  - Postfix before 3.8.16, 3.9 before 3.9.10, and 3.10 before 3.10.9 sometimes allows a buffer over-read and     process crash via an enhanced status code that lacks text after the third number. (CVE-2026-43964)

  - Improper encoding of non-finite floating-point values during MapMessage JSON serialization in Apache Log4j     API produces output that is not valid JSON. This issue affects Apache Log4j API versions 2.13.1 through     2.25.4 and version 2.26.0. The fix for CVE-2026-34481 did not cover all code paths: when a MapMessage     contains a non-finite IEEE 754 value (NaN, Infinity, or -Infinity), MapMessage.asJson() emits the     corresponding bare token. RFC 8259 does not permit these tokens, so a conformant parser rejects the     resulting document. The defect is reachable only when both of the following conditions hold: * The     application uses the message resolver https://logging.apache.org/log4j/2.x/manual/json-template-     layout.html#event-template-resolver-message of JsonTemplateLayout or any other layout that relies on     MapMessage.asJson() or MapMessage.getFormattedMessage(new String[]{JSON}). * The application logs a     MapMessage that contains an attacker-controlled floating-point value. An attacker who can supply a non-     finite value can cause the affected layout to emit malformed JSON, which may corrupt the enclosing log     record or disrupt downstream log ingestion and parsing. Users are advised to upgrade to Apache Log4j API     2.25.5 or 2.26.1, both of which emit RFC 8259-compliant JSON for non-finite values. (CVE-2026-49844)

  - An authentication bypass vulnerability exists in the OAuth2 TokenIntrospectionService in Apache CXF. Due     to a missing 'throw' keyword in the security context check, the introspection endpoint     (/services/oauth2/introspect) can be accessed by any unauthenticated network attacker. However note that     this is a safeguard only in the case that someone forgot to enable authentication on the service. Users     are recommended to upgrade to version 4.2.2 or 4.1.7 or 3.6.12, which fixes this issue. (CVE-2026-50623)

  - The 'clientId' parameter from incoming HTTP requests is directly concatenated into OAuth2 server log     warning messages without sanitizing control characters. This allows an attacker to inject arbitrary     content, including fake log entries, into the server's log files. Users are recommended to upgrade to     versions 4.2.2 or 4.1.7 or 3.6.12, which fixes this issue. (CVE-2026-50629)

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Issue summary: Applications using RSASVE key encapsulation to establish a secret encryption key can send     contents of an uninitialized memory buffer to a malicious peer. Impact summary: The uninitialized buffer     might contain sensitive data from the previous execution of the application process which leads to     sensitive data leakage to an attacker. RSA_public_encrypt() returns the number of bytes written on success     and -1 on error. The affected code tests only whether the return value is non-zero. As a result, if RSA     encryption fails, encapsulation can still return success to the caller, set the output lengths, and leave     the caller to use the contents of the ciphertext buffer as if a valid KEM ciphertext had been produced. If     applications use EVP_PKEY_encapsulate() with RSA/RSASVE on an attacker-supplied invalid RSA public key     without first validating that key, then this may cause stale or uninitialized contents of the caller-     provided ciphertext buffer to be disclosed to the attacker in place of the KEM ciphertext. As a workaround     calling EVP_PKEY_public_check() or EVP_PKEY_public_check_quick() before EVP_PKEY_encapsulate() will     mitigate the issue. The FIPS modules in 3.6, 3.5, 3.4, 3.3, 3.1 and 3.0 are affected by this issue.
    (CVE-2026-31790)

Note that Nessus relies on the presence of the package as reported by the vendor.
