Vulnerabilities 3

  • High 7.5

    BIND 9 resolvers configured to answer from stale cache with zero stale-answer-client-timeout may terminate unexpectedly

    By sending specific queries to the resolver, an attacker can cause named to crash.

  • High 7.5

    Memory leak in ECDSA DNSSEC verification code

    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.

  • High 7.5

    Memory leaks in EdDSA DNSSEC verification code

    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.
