CVE-2019-14907 – samba: Crash after failed character conversion at log level 3 or above
https://notcve.org/view.php?id=CVE-2019-14907
21 Jan 2020 — All samba versions 4.9.x before 4.9.18, 4.10.x before 4.10.12 and 4.11.x before 4.11.5 have an issue where if it is set with "log level = 3" (or above) then the string obtained from the client, after a failed character conversion, is printed. Such strings can be provided during the NTLMSSP authentication exchange. In the Samba AD DC in particular, this may cause a long-lived process(such as the RPC server) to terminate.

CVE-2019-9511 – Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service
https://notcve.org/view.php?id=CVE-2019-9511
13 Aug 2019 — Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. Algunas implementaciones de HTTP / 2 son vulnerables a la manip... • https://github.com/flyniu666/ingress-nginx-0.21-1.19.5 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
