{"id":"UBUNTU-CVE-2018-1301","details":"A specially crafted request could have crashed the Apache HTTP Server prior to version 2.4.30, due to an out of bound access after a size limit is reached by reading the HTTP header. This vulnerability is considered very hard if not impossible to trigger in non-debug mode (both log and build level), so it is classified as low risk for common server usage.","modified":"2026-04-22T12:51:18.591808Z","published":"2018-03-26T00:00:00Z","related":["USN-3627-1","USN-3627-2","USN-3937-2"],"upstream":["CVE-2018-1301"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2018-1301"},{"type":"REPORT","url":"http://www.openwall.com/lists/oss-security/2018/03/24/2"},{"type":"REPORT","url":"https://httpd.apache.org/security/vulnerabilities_24.html"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-3627-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-3627-2"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-3937-2"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2018-1301"}],"affected":[{"package":{"name":"apache2","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/apache2@2.4.7-1ubuntu4.20?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.7-1ubuntu4.20"}]}],"versions":["2.4.6-2ubuntu2","2.4.6-2ubuntu3","2.4.6-2ubuntu4","2.4.7-1ubuntu1","2.4.7-1ubuntu2","2.4.7-1ubuntu3","2.4.7-1ubuntu4","2.4.7-1ubuntu4.1","2.4.7-1ubuntu4.4","2.4.7-1ubuntu4.5","2.4.7-1ubuntu4.6","2.4.7-1ubuntu4.7","2.4.7-1ubuntu4.8","2.4.7-1ubuntu4.9","2.4.7-1ubuntu4.10","2.4.7-1ubuntu4.11","2.4.7-1ubuntu4.13","2.4.7-1ubuntu4.15","2.4.7-1ubuntu4.16","2.4.7-1ubuntu4.17","2.4.7-1ubuntu4.18","2.4.7-1ubuntu4.19"],"ecosystem_specific":{"availability":"No
