{"id":"CVE-2018-1303","details":"A specially crafted HTTP request header could have crashed the Apache HTTP Server prior to version 2.4.30 due to an out of bound read while preparing data to be cached in shared memory. It could be used as a Denial of Service attack against users of mod_cache_socache. The vulnerability is considered as low risk since mod_cache_socache is not widely used, mod_cache_disk is not concerned by this vulnerability.","modified":"2026-04-16T06:18:55.329675131Z","published":"2018-03-26T15:29:00.523Z","related":["SUSE-SU-2018:0879-1","SUSE-SU-2018:0901-1","SUSE-SU-2018:1161-1","SUSE-SU-2018:1161-2"],"references":[{"type":"WEB","url":"https://lists.apache.org/thread.html/r76142b8c5119df2178be7c2dba88fde552eedeec37ea993dfce68d1d%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rd18c3c43602e66f9cdcf09f1de233804975b9572b0456cc582390b6f%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/re473305a65b4db888e3556e4dae10c2a04ee89dcff2e26ecdbd860a9%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/56c2e7cc9deb1c12a843d0dc251ea7fd3e7e80293cde02fcd65286ba%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r9f93cf6dde308d42a9c807784e8102600d0397f5f834890708bf6920%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://www.tenable.com/security/tns-2019-09"},{"type":"WEB","url":"https://lists.apache.org/thread.html/84a3714f0878781f6ed84473d1a503d2cc382277e100450209231830%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r06f0d87ebb6d59ed8379633f36f72f5b1f79cadfda72ede0830b42cf%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rc998b18880df98bafaade071346690c2bc1444adaa1a1ea464b93f0a%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/re3d27b6250aa8548b8845d314bb8a350b3df326cacbbfdfe4d455234%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rf6449464fd8b7437704c55f88361b66f12d5b5f90bcce66af4be4ba9%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rfcf929bd33a6833e3f0c35eebdad70d5060665f9c4e17ea467c66770%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r15f9aa4427581a1aecb4063f1b4b983511ae1c9935e2a0a6876dad3c%40%3Ccvs.httpd.apache.org%3E"},{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2018/03/24/3"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/103522"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:3558"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20180601-0004/"},{"type":"ADVISORY","url":"https://www.debian.org/security/2018/dsa-4164"},{"type":"ADVISORY","url":"http://www.securitytracker.com/id/1040572"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:0367"},{"type":"ADVISORY","url":"https://httpd.apache.org/security/vulnerabilities_24.html"},{"type":"ADVISORY","url":"https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbux03909en_us"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/3627-1/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/3627-2/"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2019:0366"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/apache/httpd","events":[{"introduced":"0"},{"last_affected":"a168e4e5bab311688e66564ad230f32818adbacc"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"2.4.29"}]}}],"versions":["2.4.29"],"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"8.0"}]},{"events":[{"introduced":"0"},{"last_affected":"9.0"}]},{"events":[{"introduced":"0"},{"last_affected":"14.04"}]},{"events":[{"introduced":"0"},{"last_affected":"16.04"}]},{"events":[{"introduced":"0"},{"last_affected":"17.10"}]},{"events":[{"introduced":"0"},{"last_affected":"18.04"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2018-1303.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:N/I:N/A:H"}]}
