{"id":"CVE-2019-6256","details":"A Denial of Service issue was discovered in the LIVE555 Streaming Media libraries as used in Live555 Media Server 0.93. It can cause an RTSPServer crash in handleHTTPCmd_TunnelingPOST, when RTSP-over-HTTP tunneling is supported, via x-sessioncookie HTTP headers in a GET request and a POST request within the same TCP session. This occurs because of a call to an incorrect virtual function pointer in the readSocket function in GroupsockHelper.cpp.","modified":"2026-03-15T22:31:49.756817Z","published":"2019-01-14T08:29:00.427Z","related":["openSUSE-SU-2019:0058-1","openSUSE-SU-2024:11023-1"],"references":[{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202005-06"},{"type":"ADVISORY","url":"https://www.debian.org/security/2019/dsa-4408"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2019/02/msg00037.html"},{"type":"REPORT","url":"https://seclists.org/bugtraq/2019/Mar/22"},{"type":"EVIDENCE","url":"https://github.com/rgaufman/live555/issues/19"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"0.93"}]},{"events":[{"introduced":"0"},{"last_affected":"8.0"}]},{"events":[{"introduced":"0"},{"last_affected":"9.0"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2019-6256.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
