CVE-2020-8617 [MEDIUM] CWE-617 CVE-2020-8617: Using a specially-crafted message, an attacker may potentially cause a BIND server to reach an incon 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 BIN

In a

CVE-2020-8625 [HIGH] CWE-120 CVE-2020-8625: BIND servers are vulnerable if they are running an affected version and are configured to use GSS-TS BIND servers are vulnerable if they are running an affected version and are configured to use GSS-TSIG features. In a configuration which uses BIND's default settings the vulnerable code path is not exposed, but a server can be rendered vulnerable by explicitly setting valid values for the tkey-gssapi-keytab or tkey-gssapi-credentialconfiguration option

CVE-2023-50387 [HIGH] bind9 vulnerabilities bind9 vulnerabilities Elias Heftrig, Haya Schulmann, Niklas Vogel, and Michael Waidner discovered that Bind icorrectly handled validating DNSSEC messages. A remote attacker could possibly use this issue to cause Bind to consume resources, leading to a denial of service. (CVE-2023-50387) It was discovered that Bind incorrectly handled preparing an NSEC3 closest encloser proof. A remote attacker could possibly use this issue to cause Bind to consume re

However, a defect in this feature makes it easy, when the feature is in use, to experience an

CVE-2023-50868 [HIGH] CVE-2023-50868: The Closest Encloser Proof aspect of the DNS protocol (in RFC 5155 when RFC 9276 guidance is skipped) allows remote attackers to cause a denial of ser The Closest Encloser Proof aspect of the DNS protocol (in RFC 5155 when RFC 9276 guidance is skipped) allows remote attackers to cause a denial of service (CPU consumption for SHA-1 computations) via DNSSEC responses in a random subdomain attack, aka the "NSEC3" issue. The RFC 5155 specification implies that a
