CVE-2023-5517

A flaw in query-handling code can cause named to exit prematurely with an assertion failure when: - nxdomain-redirect ; is configured, and - the resolver receives a PTR query for an RFC 1918 address that would normally result in an authoritative NXDOMAIN response. This issue affects BIND 9 versio...

CVE-2023-4408 Parsing large DNS messages may cause excessive CPU load

The DNS message parsing code in named includes a section whose computational complexity is overly high. It does not cause problems for typical DNS traffic, but crafted queries and responses may cause excessive CPU load on the affected named instance by exploiting this flaw. This issue affects bot...

CVE-2023-4408

The DNS message parsing code in "named" includes a section whose computational complexity is overly high. It does not cause problems for typical DNS traffic, but crafted queries and responses may cause excessive CPU load on the affected "named" instance by exploiting this flaw. This issue affects...

CVE-2023-4408

The CVE-2023-4408 issue is a vulnerability in the DNS message parsing of BIND's named where the parsing path has an overly high computational complexity. A crafted large or malformed DNS message can cause high CPU usage on affected BIND 9 releases, potentially impacting both authoritative servers...

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...

ISC BIND Security Vulnerability

ISC BIND is a suite of open source software that implements the DNS protocol from the US company ISC. A security vulnerability exists in ISC BIND that stems from a specific recursive query pattern that may result in out of memory...

UBUNTU-CVE-2023-5517

A flaw in query-handling code can cause named to exit prematurely with an assertion failure when: - nxdomain-redirect ; is configured, and - the resolver receives a PTR query for an RFC 1918 address that would normally result in an authoritative NXDOMAIN response. This issue affects BIND 9 versio...

CVE-2023-6516: Allocation of Resources Without Limits or Throttling

To keep its cache database efficient, named running as a recursive resolver occasionally attempts to clean up the database. It uses several methods, including some that are asynchronous: a small chunk of memory pointing to the cache element that can be cleaned up is first allocated and then queue...

CVE-2023-4408: Inefficient Algorithmic Complexity

The DNS message parsing code in named includes a section whose computational complexity is overly high. It does not cause problems for typical DNS traffic, but crafted queries and responses may cause excessive CPU load on the affected named instance by exploiting this flaw. This issue affects bot...

CVE-2023-5680: Undefined Security Weakness

If a resolver cache has a very large number of ECS records stored for the same name, the process of cleaning the cache database node for this name can significantly impair query performance. This issue affects BIND 9 versions 9.11.3-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.45-S1, and...

CVE-2023-5517: Reachable Assertion
