A client using a TCP-pipelined connection to a server could consume more resources than the server has been provisioned to handle. When a TCP connection with a large number of pipelined queries is closed, the load on the server releasing these multiple resources can cause it to become unresponsive, even for queries that can be answered authoritatively or from cache. (This is most likely to be perceived as an intermittent server problem).", "references": ["https://kb.isc.org/docs/cve-2019-6477", "https://www.synology.com/security/advisory/Synology_SA_19_39", "https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XGURMGQHX45KR4QDRCSUQHODUFOGNGAN/"], "fixes": ["1:9.11.3+dfsg-1ubuntu1.11"], "products": [{"name": "bind9", "path": "vulns/ubuntu-18.04-lts/bind9", "ecosystem": "Ubuntu:18.04:LTS"}]}, {"id": "CVE-2019-6471", "noindex": false, "published": "2019-10-09T14:17:14.566Z", "modified": "2024-09-17T01:56:17.224Z", "cvss": 5.9, "cvss_vector": "CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H", "severity": "medium", "epss": 0.03298, "kev": false, "exploits": [], "stacks": [{"name": "system", "path": "vulns/stack/system", "slug": "system"}], "path": "vulns/cve-2019-6471", "title": "A race condition when discarding malformed packets can cause BIND to exit with an assertion failure", "description": "A race condition which may occur when discarding malformed packets can result in BIND exiting due to a REQUIRE assertion failure in dispatch.c.
