{"id":"CVE-2017-9788","details":"In Apache httpd before 2.2.34 and 2.4.x before 2.4.27, the value placeholder in [Proxy-]Authorization headers of type 'Digest' was not initialized or reset before or between successive key=value assignments by mod_auth_digest. Providing an initial key with no '=' assignment could reflect the stale value of uninitialized pool memory used by the prior request, leading to leakage of potentially confidential information, and a segfault in other cases resulting in denial of service.","modified":"2026-04-16T06:15:34.513169236Z","published":"2017-07-13T16:29:00.227Z","related":["SUSE-SU-2017:1961-1","SUSE-SU-2017:1997-1","SUSE-SU-2017:2449-1","SUSE-SU-2017:2756-1"],"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/f7f95ac1cd9895db2714fa3ebaa0b94d0c6df360f742a40951384a53%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/rad01d817195e6cc871cb1d73b207ca326379a20a6e7f30febaf56d24%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/rcc44594d4d6579b90deccd4536b5d31f099ef563df39b094be286b9e%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/rc998b18880df98bafaade071346690c2bc1444adaa1a1ea464b93f0a%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r15f9aa4427581a1aecb4063f1b4b983511ae1c9935e2a0a6876dad3c%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/r6521a7f62276340eabdb3339b2aa9a38c5f59d978497a1f794af53be%40%3Ccvs.httpd.apache.org%3E"},{"type":"WEB","url":"https://lists.apache.org/thread.html/r8c9983f1172a3415f915ddb7e14de632d2d0c326eb1285755a024165%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/0dd69204a6bd643cc4e9ccd008f07a9375525d977c6ebeb07a881afb%40%3Cannounce.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/r9ea3538f229874c80a10af473856a81fbf5f694cd7f471cc679ba70b%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/rfbaf647d52c1cb843e726a0933f156366a806cead84fbd430951591b%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/84a3714f0878781f6ed84473d1a503d2cc382277e100450209231830%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/rdca61ae990660bacb682295f2a09d34612b7bb5f457577fe17f4d064%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/thread.html/re3d27b6250aa8548b8845d314bb8a350b3df326cacbbfdfe4d455234%40%3Ccvs.httpd.apache.org%3E"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:2478"},{"type":"ADVISORY","url":"https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbux03908en_us"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:3193"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20170911-0002/"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:3113"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:2483"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:2708"},{"type":"ADVISORY","url":"https://httpd.apache.org/security/vulnerabilities_24.html"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/201710-32"},{"type":"ADVISORY","url":"https://support.apple.com/HT208221"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:3240"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:2710"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:3114"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/99569"},{"type":"ADVISORY","url":"http://www.securitytracker.com/id/1038906"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:2709"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:3195"},{"type":"ADVISORY","url":"http://www.debian.org/security/2017/dsa-3913"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2017:2479"},{"type":"ADVISORY
