The remote Oracle Linux 6 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2021-9137 advisory.

    [1.0.1e-59.0.1]
    - Backport fixes for CVE-2020-1971 [Orabug: 32654738]

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

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

According to the version of the openssl packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability :

  - The X.509 GeneralName type is a generic type for     representing different types of names. One of those     name types is known as EDIPartyName. OpenSSL provides a     function GENERAL_NAME_cmp which compares different     instances of a GENERAL_NAME to see if they are equal or     not. This function behaves incorrectly when both     GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer     dereference and a crash may occur leading to a possible     denial of service attack. OpenSSL itself uses the     GENERAL_NAME_cmp function for two purposes: 1)     Comparing CRL distribution point names between an     available CRL and a CRL distribution point embedded in     an X509 certificate 2) When verifying that a timestamp     response token signer matches the timestamp authority     name (exposed via the API functions     TS_RESP_verify_response and TS_RESP_verify_token) If an     attacker can control both items being compared then     that attacker could trigger a crash. For example if the     attacker can trick a client or server into checking a     malicious certificate against a malicious CRL then this     may occur. Note that some applications automatically     download CRLs based on a URL embedded in a certificate.
    This checking happens prior to the signatures on the     certificate and CRL being verified. OpenSSL's s_server,     s_client and verify tools have support for the     '-crl_download' option which implements automatic CRL     downloading and this attack has been demonstrated to     work against those tools. Note that an unrelated bug     means that affected versions of OpenSSL cannot parse or     construct correct encodings of EDIPARTYNAME. However it     is possible to construct a malformed EDIPARTYNAME that     OpenSSL's parser will accept and hence trigger this     attack. All OpenSSL 1.1.1 and 1.0.2 versions are     affected by this issue. Other OpenSSL releases are out     of support and have not been checked. Fixed in OpenSSL     1.1.1i (Affected 1.1.1-1.1.1h). Fixed in OpenSSL 1.0.2x     (Affected 1.0.2-1.0.2w).(CVE-2020-1971)

Node.js reports : use-after-free in TLSWrap (High) (CVE-2020-8265) Affected Node.js versions are vulnerable to a use-after-free bug in its TLS implementation. When writing to a TLS enabled socket, node::StreamBase::Write calls node::TLSWrap::DoWrite with a freshly allocated WriteWrap object as first argument. If the DoWrite method does not return an error, this object is passed back to the caller as part of a StreamWriteResult structure. This may be exploited to corrupt memory leading to a Denial of Service or potentially other exploits. HTTP Request Smuggling in nodejs (Low) (CVE-2020-8287) Affected versions of Node.js allow two copies of a header field in a http request. For example, two Transfer-Encoding header fields. In this case Node.js identifies the first header field and ignores the second. This can lead to HTTP Request Smuggling. OpenSSL - EDIPARTYNAME NULL pointer de-reference (CVE-2020-1971) iThis is a vulnerability in OpenSSL which may be exploited through Node.js. You can read more about it in https://www.openssl.org/news/secadv/20201208.txt.

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

  - While parsing an IPAddressFamily extension in an X.509 certificate, it is possible to do a one-byte     overread. This would result in an incorrect text display of the certificate. This bug has been present     since 2006 and is present in all versions of OpenSSL before 1.0.2m and 1.1.0g. (CVE-2017-3735)

  - OpenSSL 1.0.2 (starting from version 1.0.2b) introduced an 'error state' mechanism. The intent was that if     a fatal error occurred during a handshake then OpenSSL would move into the error state and would     immediately fail if you attempted to continue the handshake. This works as designed for the explicit     handshake functions (SSL_do_handshake(), SSL_accept() and SSL_connect()), however due to a bug it does not     work correctly if SSL_read() or SSL_write() is called directly. In that scenario, if the handshake fails     then a fatal error will be returned in the initial function call. If SSL_read()/SSL_write() is     subsequently called by the application for the same SSL object then it will succeed and the data is passed     without being decrypted/encrypted directly from the SSL/TLS record layer. In order to exploit this issue     an application bug would have to be present that resulted in a call to SSL_read()/SSL_write() being issued     after having already received a fatal error. OpenSSL version 1.0.2b-1.0.2m are affected. Fixed in OpenSSL     1.0.2n. OpenSSL 1.1.0 is not affected. (CVE-2017-3737)

  - During key agreement in a TLS handshake using a DH(E) based ciphersuite a malicious server can send a very     large prime value to the client. This will cause the client to spend an unreasonably long period of time     generating a key for this prime resulting in a hang until the client has finished. This could be exploited     in a Denial Of Service attack. Fixed in OpenSSL 1.1.0i-dev (Affected 1.1.0-1.1.0h). Fixed in OpenSSL     1.0.2p-dev (Affected 1.0.2-1.0.2o). (CVE-2018-0732)

  - The OpenSSL RSA Key generation algorithm has been shown to be vulnerable to a cache timing side channel     attack. An attacker with sufficient access to mount cache timing attacks during the RSA key generation     process could recover the private key. Fixed in OpenSSL 1.1.0i-dev (Affected 1.1.0-1.1.0h). Fixed in     OpenSSL 1.0.2p-dev (Affected 1.0.2b-1.0.2o). (CVE-2018-0737)

  - Constructed ASN.1 types with a recursive definition (such as can be found in PKCS7) could eventually     exceed the stack given malicious input with excessive recursion. This could result in a Denial Of Service     attack. There are no such structures used within SSL/TLS that come from untrusted sources so this is     considered safe. Fixed in OpenSSL 1.1.0h (Affected 1.1.0-1.1.0g). Fixed in OpenSSL 1.0.2o (Affected     1.0.2b-1.0.2n). (CVE-2018-0739)

  - In situations where an attacker receives automated notification of the success or failure of a decryption     attempt an attacker, after sending a very large number of messages to be decrypted, can recover a     CMS/PKCS7 transported encryption key or decrypt any RSA encrypted message that was encrypted with the     public RSA key, using a Bleichenbacher padding oracle attack. Applications are not affected if they use a     certificate together with the private RSA key to the CMS_decrypt or PKCS7_decrypt functions to select the     correct recipient info to decrypt. Fixed in OpenSSL 1.1.1d (Affected 1.1.1-1.1.1c). Fixed in OpenSSL     1.1.0l (Affected 1.1.0-1.1.0k). Fixed in OpenSSL 1.0.2t (Affected 1.0.2-1.0.2s). (CVE-2019-1563)

  - The X.509 GeneralName type is a generic type for representing different types of names. One of those name     types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different     instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both     GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a     possible denial of service attack. OpenSSL itself uses the GENERAL_NAME_cmp function for two purposes: 1)     Comparing CRL distribution point names between an available CRL and a CRL distribution point embedded in     an X509 certificate 2) When verifying that a timestamp response token signer matches the timestamp     authority name (exposed via the API functions TS_RESP_verify_response and TS_RESP_verify_token) If an     attacker can control both items being compared then that attacker could trigger a crash. For example if     the attacker can trick a client or server into checking a malicious certificate against a malicious CRL     then this may occur. Note that some applications automatically download CRLs based on a URL embedded in a     certificate. This checking happens prior to the signatures on the certificate and CRL being verified.
    OpenSSL's s_server, s_client and verify tools have support for the '-crl_download' option which implements     automatic CRL downloading and this attack has been demonstrated to work against those tools. Note that an     unrelated bug means that affected versions of OpenSSL cannot parse or construct correct encodings of     EDIPARTYNAME. However it is possible to construct a malformed EDIPARTYNAME that OpenSSL's parser will     accept and hence trigger this attack. All OpenSSL 1.1.1 and 1.0.2 versions are affected by this issue.
    Other OpenSSL releases are out of support and have not been checked. Fixed in OpenSSL 1.1.1i (Affected     1.1.1-1.1.1h). Fixed in OpenSSL 1.0.2x (Affected 1.0.2-1.0.2w). (CVE-2020-1971)

  - 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)

  - The OpenSSL public API function X509_issuer_and_serial_hash() attempts to create a unique hash value based     on the issuer and serial number data contained within an X509 certificate. However it fails to correctly     handle any errors that may occur while parsing the issuer field (which might occur if the issuer field is     maliciously constructed). This may subsequently result in a NULL pointer deref and a crash leading to a     potential denial of service attack. The function X509_issuer_and_serial_hash() is never directly called by     OpenSSL itself so applications are only vulnerable if they use this function directly and they use it on     certificates that may have been obtained from untrusted sources. 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-2021-23841)
