Denial Of Service (DoS)

libbind9.so is vulnerable to denial of service. The vulnerability exists because the DNSSEC verification code used in the library for the ECDSA algorithm leaks memory when the signature length is mismatched, allowing an attacker to cause an application crash...

USN-5626-2 bind9 vulnerabilities

USN-5626-1 fixed several vulnerabilities in Bind. This update provides the corresponding update for Ubuntu 14.04 ESM and Ubuntu 16.04 ESM. Original advisory details: Yehuda Afek, Anat Bremler-Barr, and Shani Stajnrod discovered that Bind incorrectly handled large delegations. A remote attacker...

CVE-2022-38178

A flaw was found in the Bind package, where the DNSSEC verification code for the EdDSA algorithm leaks memory when there is a signature length mismatch. By spoofing the target resolver with responses that have a malformed EdDSA signature, an attacker can trigger a small memory leak, resulting in...

USN-5626-1: Bind vulnerabilities

Yehuda Afek, Anat Bremler-Barr, and Shani Stajnrod discovered that Bind incorrectly handled large delegations. A remote attacker could possibly use this issue to reduce performance, leading to a denial of service. CVE-2022-2795 It was discovered that Bind incorrectly handled statistics requests. ...
