{"id":"USN-3937-1","summary":"apache2 vulnerabilities","details":"Charles Fol discovered that the Apache HTTP Server incorrectly handled the\nscoreboard shared memory area. A remote attacker able to upload and run\nscripts could possibly use this issue to execute arbitrary code with root\nprivileges. (CVE-2019-0211)\n\nIt was discovered that the Apache HTTP Server HTTP/2 module incorrectly\nhandled certain requests. A remote attacker could possibly use this issue\nto cause the server to consume resources, leading to a denial of service.\nThis issue only affected Ubuntu 18.04 LTS and Ubuntu 18.10.\n(CVE-2018-17189)\n\nIt was discovered that the Apache HTTP Server incorrectly handled session\nexpiry times. When used with mod_session_cookie, this may result in the\nsession expiry time to be ignored, contrary to expectations.\n(CVE-2018-17199)\n\nCraig Young discovered that the Apache HTTP Server HTTP/2 module\nincorrectly handled certain requests. A remote attacker could possibly use\nthis issue to cause the server to process requests incorrectly. This issue\nonly affected Ubuntu 18.04 LTS and Ubuntu 18.10. (CVE-2019-0196)\n\nSimon Kappel discovered that the Apache HTTP Server mod_auth_digest module\nincorrectly handled threads. A remote attacker with valid credentials could\npossibly use this issue to authenticate using another username, bypassing\naccess control restrictions. (CVE-2019-0217)\n\nBernhard Lorenz discovered that the Apache HTTP Server was inconsistent\nwhen processing requests containing multiple consecutive slashes. This\ncould lead to directives such as LocationMatch and RewriteRule to perform\ncontrary to expectations.
