Design/Logic Flaw

A bad interaction between DNS64 and serve-stale may cause named to crash with an assertion failure during recursive resolution, when both of these features are enabled. This issue affects BIND 9 versions 9.16.12 through 9.16.45, 9.18.0 through 9.18.21, 9.19.0 through 9.19.19, 9.16.12-S1 through...

Design/Logic Flaw

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...

Design/Logic Flaw

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-2023-6516

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...

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...
