{"id":"CVE-2016-8743","details":"Apache HTTP Server, in all releases prior to 2.2.32 and 2.4.25, was liberal in the whitespace accepted from requests and sent in response lines and headers. Accepting these different behaviors represented a security concern when httpd participates in any chain of proxies or interacts with back-end application servers, either through mod_proxy or using conventional CGI mechanisms, and may result in request smuggling, response splitting and cache pollution.","modified":"2026-05-18T05:48:47.256285279Z","published":"2017-07-27T21:29:00.287Z","related":["SUSE-SU-2017:0729-1","SUSE-SU-2017:0797-1","SUSE-SU-2017:0801-1","SUSE-SU-2018:2554-1","SUSE-SU-2018:2815-1","SUSE-SU-2018:2815-2"],"database_specific":{"unresolved_ranges":[{"vendor_product":"debian:debian_linux","extracted_events":[{"last_affected":"8.0"},{"last_affected":"9.0"}],"source":"CPE_FIELD","cpes":["cpe:2.3:o:debian:debian_linux:8.0:*:*:*:*:*:*:*","cpe:2.3:o:debian:debian_linux:9.0:*:*:*:*:*:*:*"]},{"vendor_product":"redhat:enterprise_linux_desktop","extracted_events":[{"last_affected":"6.0"},{"last_affected":"7.0"}],"cpes":["cpe:2.3:o:redhat:enterprise_linux_desktop:6.0:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux_desktop:7.0:*:*:*:*:*:*:*"],"source":"CPE_FIELD"},{"vendor_product":"redhat:enterprise_linux_eus","extracted_events":[{"last_affected":"7.3"},{"last_affected":"7.4"},{"last_affected":"7.5"},{"last_affected":"7.6"},{"last_affected":"7.7"}],"source":"CPE_FIELD","cpes":["cpe:2.3:o:redhat:enterprise_linux_eus:7.3:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux_eus:7.4:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux_eus:7.5:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux_eus:7.6:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux_eus:7.7:*:*:*:*:*:*:*"]},{"vendor_product":"redhat:enterprise_linux_server","extracted_events":[{"last_affected":"6.0"},{"last_affected":"7.0"}],"cpes":["cpe:2.3:o:redhat:enterprise_linux_server:6.0:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux_server:7.0:*:*:*:*:*:*:*"],"source":"CPE_FIELD"},{"vendor_product":"redhat:enterprise_linux_server_aus","extracted_events":[{"last_affected":"7.3"},{"last_affected":"7.4"},{"last_affected":"7.6"},{"last_affected":"7.7"}],"source":"CPE_FIELD","cpes":["cpe:2.3:o:redhat:enterprise_linux_server_aus:7.3:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux_server_aus:7.4:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux_server_aus:7.6:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux_server_aus:7.7:*:*:*:*:*:*:*"]},{"vendor_product":"redhat:enterprise_linux_server_tus","extracted_events":[{"last_affected":"7.3"},{"last_affected":"7.6"},{"last_affected":"7.7"}],"source":"CPE_FIELD","cpes":["cpe:2.3:o:redhat:enterprise_linux_server_tus:7.3:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux_server_tus:7.6:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux_server_tus:7.7:*:*:*:*:*:*:*"]},{"vendor_product":"redhat:enterprise_linux_workstation","extracted_events":[{"last_affected":"6.0"},{"last_affected":"7.0"}],"cpes":["cpe:2.3:o:redhat:enterprise_linux_workstation:6.0:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux_workstation:7.0:*:*:*:*:*:*:*"],"source":"CPE_FIELD"},{"vendor_product":"redhat:jboss_core_services","extracted_events":[{"last_affected":"1.0"}],"cpes":["cpe:2.3:a:redhat:jboss_core_services:1.0:*:*:*:*:*:*:*"],"source":"CPE_FIELD"}]},"references":[{"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/84a3714f0878781f6ed84473d1a503d2cc382277e100450209231830%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/8d63cb8e9100f28a99429b4328e4e7cebce861d5772ac9863ba2ae6f%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/f7f95ac1cd9895db2714fa3ebaa0b94d0c6df360f742a40951384a53%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r04e89e873d54116a0635ef2f7061c15acc5ed27ef7500997beb65d6f%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r09b8a39d1262adbab5528eea73df1b1f93e919bf004ed5a843d9cad1%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r476d175be0aaf4a17680ef98c5153b4d336eaef76fb2224cc94c463a%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r4fe84db67fe9dc906c6185e58bbd9913f4356dd555a5c3db490694e5%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r57608dc51b79102f3952ae06f54d5277b649c86d6533dcd6a7d201f7%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r6521a7f62276340eabdb3339b2aa9a38c5f59d978497a1f794af53be%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r75cbe9ea3e2114e4271bbeca7aff96117b50c1b6eb7c4772b0337c1f%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r94284b139540e5287ebdd3450682d3e3d187263dd6b75af8fa7d4890%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r9ea3538f229874c80a10af473856a81fbf5f694cd7f471cc679ba70b%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://lists.apache.org
