https://notcve.org/view.php?id=CVE-2022-3080
By sending specific queries to the resolver, an attacker can cause named to crash. Mediante el envío de consultas específicas al resolver, un atacante puede causar la caída de named A flaw was found in the Bind package, where the resolver can crash when stale cache and stale answers are enabled, option stale-answer-client-timeout is set to 0 and there is a stale CNAME in the cache for an incoming query. By sending specific queries to the resolver, an attacker can cause named to crash. • http://www.openwall.com/lists/oss-security/2022/09/21/3 https://kb.isc.org/docs/cve-2022-3080 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CV4GQWBPF7Y52J2FA24U6UMHQAOXZEF7 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MRHB6J4Z7BKH4HPEKG5D35QGRD6ANNMT https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YZJQNUASODNVAWZV6STKG5SD6XIJ446S https://security.gentoo.org/glsa/202210-25 https://securi • CWE-20: Improper Input Validation CWE-613: Insufficient Session Expiration •
CVE-2022-38178 – Memory leaks in EdDSA DNSSEC verification code
https://notcve.org/view.php?id=CVE-2022-38178
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. Al falsificar el resolver objetivo con respuestas que presentan una firma EdDSA malformada, un atacante puede desencadenar una pequeña pérdida de memoria. Es posible erosionar gradualmente la memoria disponible hasta el punto de que named sea bloqueado por falta de recursos 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 crashing the program. • http://www.openwall.com/lists/oss-security/2022/09/21/3 https://kb.isc.org/docs/cve-2022-38178 https://lists.debian.org/debian-lts-announce/2022/10/msg00007.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CV4GQWBPF7Y52J2FA24U6UMHQAOXZEF7 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MRHB6J4Z7BKH4HPEKG5D35QGRD6ANNMT https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YZJQNUASODNVAWZV6STKG5 • CWE-401: Missing Release of Memory after Effective Lifetime •
