CVE-2023-50868

A flaw was found in bind9. By flooding a DNSSEC resolver with responses coming from a DNSEC-signed zone using NSEC3, an attacker can lead the targeted resolver to a CPU exhaustion, further leading to a Denial of Service on the targeted host. This vulnerability applies only for systems where DNSSE...

DEBIAN-CVE-2023-6516

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-2023-5680

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

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...

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-2023-6516

CVE-2023-6516 affects ISC BIND (named) as a denial-of-service vector via an out-of-memory condition in the cache-cleanup path when recursive queries trigger maintenance. The issue can allow memory usage to exceed max-cache-size, potentially causing DoS on vulnerable BIND 9 installations. Affected...
