{"id":"CVE-2015-5600","details":"The kbdint_next_device function in auth2-chall.c in sshd in OpenSSH through 6.9 does not properly restrict the processing of keyboard-interactive devices within a single connection, which makes it easier for remote attackers to conduct brute-force attacks or cause a denial of service (CPU consumption) via a long and duplicative list in the ssh -oKbdInteractiveDevices option, as demonstrated by a modified client that provides a different password for each pam element on this list.","modified":"2026-04-16T06:15:23.315021643Z","published":"2015-08-03T01:59:03Z","related":["SUSE-SU-2015:1544-1","SUSE-SU-2015:1581-1","SUSE-SU-2015:1695-1","SUSE-SU-2015:1840-1"],"references":[{"type":"ADVISORY","url":"http://rhn.redhat.com/errata/RHSA-2016-0466.html"},{"type":"ADVISORY","url":"http://www.oracle.com/technetwork/security-advisory/cpujul2016-2881720.html"},{"type":"ADVISORY","url":"http://www.oracle.com/technetwork/security-advisory/cpujul2018-4258247.html"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-2710-1"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-2710-2"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/201512-04"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20151106-0001/"},{"type":"ADVISORY","url":"https://www.arista.com/en/support/advisories-notices/security-advisories/1174-security-advisory-12"},{"type":"EVIDENCE","url":"http://seclists.org/fulldisclosure/2015/Jul/92"},{"type":"WEB","url":"http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/auth2-chall.c"},{"type":"WEB","url":"http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/auth2-chall.c.diff?r1=1.42&r2=1.43&f=h"},{"type":"WEB","url":"http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10697"},{"type":"WEB","url":"http://lists.apple.com/archives/security-announce/2015/Aug/msg00001.html"},{"type":"WEB","url":"http://lists.fedoraproject.org/pipermail/package-announce/2015-August/165170.html"},{"type":"WEB","url":"http://lists.fedoraproject.org/pipermail/package-announce/2015-July/162955.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00017.html"},{"type":"WEB","url":"http://openwall.com/lists/oss-security/2015/07/23/4"},{"type":"WEB","url":"http://www.oracle.com/technetwork/topics/security/bulletinoct2015-2511968.html"},{"type":"WEB","url":"http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html"},{"type":"WEB","url":"http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2015-2719645.html"},{"type":"WEB","url":"http://www.oracle.com/technetwork/topics/security/ovmbulletinjul2016-3090546.html"},{"type":"WEB","url":"http://www.securityfocus.com/bid/75990"},{"type":"WEB","url":"http://www.securityfocus.com/bid/91787"},{"type":"WEB","url":"http://www.securityfocus.com/bid/92012"},{"type":"WEB","url":"http://www.securitytracker.com/id/1032988"},{"type":"WEB","url":"https://cert-portal.siemens.com/productcert/pdf/ssa-412672.pdf"},{"type":"WEB","url":"https://h20564.www2.hpe.com/portal/site/hpsc/public/kb/docDisplay?docId=emr_na-c04952480"},{"type":"WEB","url":"https://h20566.www2.hpe.com/portal/site/hpsc/public/kb/docDisplay?docId=emr_na-c05128992"},{"type":"WEB","url":"https://h20566.www2.hpe.com/portal/site/hpsc/public/kb/docDisplay?docId=emr_na-c05157667"},{"type":"WEB","url":"https://kc.mcafee.com/corporate/index?page=content&id=SB10136"},{"type":"WEB","url":"https://kc.mcafee.com/corporate/index?page=content&id=SB10157"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2018/09/msg00010.html"},{"type":"WEB","url":"https://support.apple.com/kb/HT205031"}],"schema_version":"1.7.5"}
