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 :

  - An OpenSSL TLS server may crash if sent a maliciously     crafted renegotiation ClientHello message from a     client. If a TLSv1.2 renegotiation ClientHello omits     the signature_algorithms extension (where it was     present in the initial ClientHello), but includes a     signature_algorithms_cert extension then a NULL pointer     dereference will result, leading to a crash and a     denial of service attack. A server is only vulnerable     if it has TLSv1.2 and renegotiation enabled (which is     the default configuration). OpenSSL TLS clients are not     impacted by this issue. All OpenSSL 1.1.1 versions are     affected by this issue. Users of these versions should     upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not     impacted by this issue. Fixed in OpenSSL 1.1.1k     (Affected 1.1.1-1.1.1j).(CVE-2021-3449)

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.

The remote SUSE Linux SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:2327-1 advisory.

  - The package y18n before 3.2.2, 4.0.1 and 5.0.5, is vulnerable to Prototype Pollution. (CVE-2020-7774)

  - Node.js before 16.4.1, 14.17.2, 12.22.2 is vulnerable to an out-of-bounds read when uv__idna_toascii() is     used to convert strings to ASCII. The pointer p is read and increased without checking whether it is     beyond pe, with the latter holding a pointer to the end of the buffer. This can lead to information     disclosures or crashes. This function can be triggered via uv_getaddrinfo(). (CVE-2021-22918)

  - The package hosted-git-info before 3.0.8 are vulnerable to Regular Expression Denial of Service (ReDoS)     via regular expression shortcutMatch in the fromUrl function in index.js. The affected regular expression     exhibits polynomial worst-case time complexity. (CVE-2021-23362)

  - ssri 5.2.2-8.0.0, fixed in 8.0.1, processes SRIs using a regular expression which is vulnerable to a     denial of service. Malicious SRIs could take an extremely long time to process, leading to denial of     service. This issue only affects consumers using the strict option. (CVE-2021-27290)

  - An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a     client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was     present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL     pointer dereference will result, leading to a crash and a denial of service attack. A server is only     vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS     clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of     these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in     OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j). (CVE-2021-3449)

  - The X509_V_FLAG_X509_STRICT flag enables additional security checks of the certificates present in a     certificate chain. It is not set by default. Starting from OpenSSL version 1.1.1h a check to disallow     certificates in the chain that have explicitly encoded elliptic curve parameters was added as an     additional strict check. An error in the implementation of this check meant that the result of a previous     check to confirm that certificates in the chain are valid CA certificates was overwritten. This     effectively bypasses the check that non-CA certificates must not be able to issue other certificates. If a     purpose has been configured then there is a subsequent opportunity for checks that the certificate is a     valid CA. All of the named purpose values implemented in libcrypto perform this check. Therefore, where     a purpose is set the certificate chain will still be rejected even when the strict flag has been used. A     purpose is set by default in libssl client and server certificate verification routines, but it can be     overridden or removed by an application. In order to be affected, an application must explicitly set the     X509_V_FLAG_X509_STRICT verification flag and either not set a purpose for the certificate verification     or, in the case of TLS client or server applications, override the default purpose. OpenSSL versions     1.1.1h and newer are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k.
    OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1h-1.1.1j).
    (CVE-2021-3450)

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

A NULL pointer dereference was found in the signature_algorithms processing in OpenSSL, a Secure Sockets Layer toolkit, which could result in denial of service.
