13 Jul 2021 — 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 Affected devices con... • https://cert-portal.siemens.com/productcert/pdf/ssa-599968.pdf • 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
25 Mar 2021 — 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 c... • https://github.com/riptl/cve-2021-3449 • CWE-476: NULL Pointer Dereference •

CVE-2019-13946
https://notcve.org/view.php?id=CVE-2019-13946
11 Feb 2020 — Profinet-IO (PNIO) stack versions prior V06.00 do not properly limit internal resource allocation when multiple legitimate diagnostic package requests are sent to the DCE-RPC interface. This could lead to a denial of service condition due to lack of memory for devices that include a vulnerable version of the stack. The security vulnerability could be exploited by an attacker with network access to an affected device. Successful exploitation requires no system privileges and no user interaction. An attacker ... • https://cert-portal.siemens.com/productcert/html/ssa-780073.html • CWE-400: Uncontrolled Resource Consumption •
