Server or client applications that call the SSL_check_chain() function during or after a TLS 1.3 handshake may crash due to a NULL pointer dereference as a result of incorrect handling of the "signature_algorithms_cert" TLS extension. The crash occurs if an invalid or unrecognised signature algorithm is received from the peer. This could be exploited by a malicious peer in a Denial of Service attack. OpenSSL version 1.1.1d, 1.1.1e, and 1.1.1f are affected by this issue. This issue did not affect OpenSSL versions prior to 1.1.1d. Fixed in OpenSSL 1.1.1g (Affected 1.1.1d-1.1.1f).

An update of the nxtgn package has been released.

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

  - 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)

  - A NULL pointer dereference flaw was found in the way     OpenSSL handled certain TLS handshake messages. This     flaw allows an unauthenticated attacker to cause a     server application compiled with OpenSSL to crash,     causing a denial of service. In some cases a malicious     server could also cause a client compiled with OpenSSL     to crash.(CVE-2020-1967)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to its self-reported version, the Tenable SecurityCenter application installed on the remote host is earlier than 5.17.0. It is, therefore, affected by multiple vulnerabilities.
