ISC Releases Security Advisories for BIND 9


The Internet Systems Consortium (ISC) released security advisories to address vulnerabilities affecting multiple versions of ISC’s Berkeley Internet Name Domain (BIND) 9. A cyber threat actor could exploit one of these vulnerabilities to cause a denial-of-service condition. 

CISA encourages users and administrators to review the following advisories and apply the necessary updates: 

  • CVE-2024-4076: Assertion failure when serving both stale cache data and authoritative zone content
  • CVE-2024-1975: SIG(0) can be used to exhaust CPU resources
  • CVE-2024-1737: BIND’s database will be slow if a very large number of RRs exist at the same name
  • CVE-2024-0760: A flood of DNS messages over TCP may make the server unstable
