https://notcve.org/view.php?id=CVE-2020-8616
19 May 2020 — A malicious actor who intentionally exploits this lack of effective limitation on the number of fetches performed when processing referrals can, through the use of specially crafted referrals, cause a recursing server to issue a very large number of fetches in an attempt to process the referral. This has at least two potential effects: The performance of the recursing server can potentially be degraded by the additional work required to perform these fetches, and The attacker can exploit this behavior to us... • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00041.html • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2020-8617
19 May 2020 — Using a specially-crafted message, an attacker may potentially cause a BIND server to reach an inconsistent state if the attacker knows (or successfully guesses) the name of a TSIG key used by the server. Since BIND, by default, configures a local session key even on servers whose configuration does not otherwise make use of it, almost all current BIND servers are vulnerable. In releases of BIND dating from March 2018 and after, an assertion check in tsig.c detects this inconsistent state and deliberately e... • https://packetstorm.news/files/id/180550 • CWE-617: Reachable Assertion •
