The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly.

Security Fix(es):

* bind: BIND 9 resolvers configured to answer from cache with zero stale-answer-timeout may terminate unexpectedly (CVE-2022-3080) * bind: memory leak in ECDSA DNSSEC verification code (CVE-2022-38177) * bind: memory leaks in EdDSA DNSSEC verification code (CVE-2022-38178)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

BIND (Berkeley Internet Name Domain) is an implementation of the DNS (Domain Name System) protocols. BIND includes a DNS server (named), which resolves host names to IP addresses; a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating properly. Security Fix(es): By sending specific queries to the resolver, an attacker can cause named to crash.(CVE-2022-3080) By spoofing the target resolver with responses that have a malformed ECDSA signature, an attacker can trigger a small memory leak. It is possible to gradually erode available memory to the point where named crashes for lack of resources.(CVE-2022-38177) By spoofing the target resolver with responses that have a malformed EdDSA signature, an attacker can trigger a small memory leak. It is possible to gradually erode available memory to the point where named crashes for lack of resources.(CVE-2022-38178) By flooding the target resolver with queries exploiting this flaw an attacker can significantly impair the resolver's performance, effectively denying legitimate clients access to the DNS resolution service.(CVE-2022-2795) The underlying bug might cause read past end of the buffer and either read memory it should not read, or crash the process.(CVE-2022-2881) An attacker can leverage this flaw to gradually erode available memory to the point where named crashes for lack of resources.
