CVE-2020-28400
https://notcve.org/view.php?id=CVE-2020-28400
Affected devices contain a vulnerability that allows an unauthenticated attacker to trigger a denial-of-service condition. The vulnerability can be triggered if a large amount of DCP reset packets are sent to the device. Los dispositivos afectados contienen una vulnerabilidad que permite a un atacante no autentificado desencadenar una condición de denegación de servicio. La vulnerabilidad puede activarse si se envía una gran cantidad de paquetes de restablecimiento de DCP al dispositivo • https://cert-portal.siemens.com/productcert/pdf/ssa-599968.pdf https://us-cert.cisa.gov/ics/advisories/icsa-21-194-03 https://cert-portal.siemens.com/productcert/html/ssa-599968.html • CWE-770: Allocation of Resources Without Limits or Throttling •

CVE-2021-3449 – NULL pointer deref in signature_algorithms processing
https://notcve.org/view.php?id=CVE-2021-3449
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. • http://www.openwall.com/lists/oss-security/2021/03/27/1 http://www.openwall.com/lists/oss-security/2021/03/27/2 http://www.openwall.com/lists/oss-security/2021/03/28/3 http://www.openwall.com/lists/oss-security/2021/03/28/4 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-772220.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=fb9fa6b51defd48157eeb207f52181f735d96148 https://kb.pulse • CWE-476: NULL Pointer Dereference •
