{"id":"UBUNTU-CVE-2019-15892","details":"An issue was discovered in Varnish Cache before 6.0.4 LTS, and 6.1.x and 6.2.x before 6.2.1. An HTTP/1 parsing failure allows a remote attacker to trigger an assert by sending crafted HTTP/1 requests. The assert will cause an automatic restart with a clean cache, which makes it a Denial of Service attack.","modified":"2025-07-16T07:39:42.896934Z","published":"2019-09-03T21:15:00Z","withdrawn":"2025-07-18T16:45:19Z","upstream":["CVE-2019-15892"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2019-15892"},{"type":"REPORT","url":"https://varnish-cache.org/security/VSV00003.html"},{"type":"REPORT","url":"https://github.com/varnishcache/varnish-cache/commit/1cb778f6f69737109e8c070a74b8e95b78f46d13"},{"type":"REPORT","url":"https://github.com/varnishcache/varnish-cache/commit/0f0e51e9871ed1bd1236378f8b0dea0d33df4e9e"},{"type":"REPORT","url":"https://github.com/varnishcache/varnish-cache/commit/72df38fa8bfc0f5ca4a75d3e32657e8e590d85ab"},{"type":"REPORT","url":"https://github.com/varnishcache/varnish-cache/commit/dd47e658a0de9d12c433a4a01fb43ea4fe4d3a41"},{"type":"REPORT","url":"https://github.com/varnishcache/varnish-cache/commit/34717183beda3803e3d54c9826a1a9f026ca2505"},{"type":"REPORT","url":"https://github.com/varnishcache/varnish-cache/commit/ec3997a59a93cbc13a3cba22dfe0b4c4710a8f65"},{"type":"REPORT","url":"https://github.com/varnishcache/varnish-cache/commit/af13de03eaa3d04f60ada52ed3235d545b8d3973"},{"type":"REPORT","url":"https://github.com/varnishcache/varnish-cache/commit/6da64a47beff44ecdb45c82b033811f2d19819af"},{"type":"REPORT","url":"https://seclists.org/bugtraq/2019/Sep/5"},{"type":"REPORT","url":"https://www.debian.org/security/2019/dsa-4514"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2019-15892"}],"affected":[{"package":{"name":"varnish","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/varnish@6.2.1-2?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.2.1-2"}]}],"versions":["6.1.1-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libvarnishapi-dev","binary_version":"6.2.1-2"},{"binary_name":"libvarnishapi2","binary_version":"6.2.1-2"},{"binary_version":"6.2.1-2","binary_name":"libvarnishapi2-dbgsym"},{"binary_name":"varnish","binary_version":"6.2.1-2"},{"binary_name":"varnish-dbgsym","binary_version":"6.2.1-2"},{"binary_name":"varnish-doc","binary_version":"6.2.1-2"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-15892.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
