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 Specific recursive query patterns may lead to an out-of-memory condition

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...
