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_
    _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-2026-28390)
