{"id":"SUSE-SU-2018:3776-2","summary":"Security update for openssh","details":"This update for openssh fixes the following issues:\n\nFollowing security issues have been fixed:\n\n- CVE-2018-15919: Remotely observable behaviour in auth-gss2.c in OpenSSH could be used by remote attackers to detect existence of users on a target system when GSS2 is in use. OpenSSH developers do not want to treat such a username enumeration (or 'oracle') as a vulnerability. (bsc#1106163)\n- CVE-2018-15473: OpenSSH was prone to a user existance oracle vulnerability due to not delaying bailout for an invalid authenticating user until after the packet containing the request has been fully parsed, related to auth2-gss.c, auth2-hostbased.c, and auth2-pubkey.c. (bsc#1105010)\n\nAlso the following security related hardening change was done:\n\n- Remove arcfour,cast,blowfish from list of default ciphers. (bsc#982273)\n\nAnd the following non-security issues were fixed:\n\n- Stop leaking File descriptors (bsc#964336)\n- sftp-client.c returns wrong error code upon failure (bsc#1091396)\n","modified":"2026-03-11T07:00:52.214066Z","published":"2019-04-29T06:09:11Z","related":["CVE-2018-15473"],"upstream":["CVE-2018-15473"],"references":[{"type":"ADVISORY","url":"https://www.suse.com/support/update/announcement/2018/suse-su-20183776-2/"},{"type":"REPORT","url":"https://bugzilla.suse.com/1091396"},{"type":"REPORT","url":"https://bugzilla.suse.com/1105010"},{"type":"REPORT","url":"https://bugzilla.suse.com/1106163"},{"type":"REPORT","url":"https://bugzilla.suse.com/964336"},{"type":"REPORT","url":"https://bugzilla.suse.com/982273"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2018-15473"}],"affected":[{"package":{"name":"openssh","ecosystem":"SUSE:Linux Enterprise Server for SAP Applications 12 SP1","purl":"pkg:rpm/suse/openssh&distro=SUSE%20Linux%20Enterprise%20Server%20for%20SAP%20Applications%2012%20SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6p1-54.18.1"}]}],"ecosystem_specific":{"binaries":[{"openssh-helpers":"6.6p1-54.18.1","openssh":"6.6p1-54.18.1","openssh-askpass-gnome":"6.6p1-54.18.1","openssh-fips":"6.6p1-54.18.1"}]},"database_specific":{"source":"https://ftp.suse.com/pub/projects/security/osv/SUSE-SU-2018:3776-2.json"}},{"package":{"name":"openssh-askpass-gnome","ecosystem":"SUSE:Linux Enterprise Server for SAP Applications 12 SP1","purl":"pkg:rpm/suse/openssh-askpass-gnome&distro=SUSE%20Linux%20Enterprise%20Server%20for%20SAP%20Applications%2012%20SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6p1-54.18.1"}]}],"ecosystem_specific":{"binaries":[{"openssh-askpass-gnome":"6.6p1-54.18.1","openssh-fips":"6.6p1-54.18.1","openssh-helpers":"6.6p1-54.18.1","openssh":"6.6p1-54.18.1"}]},"database_specific":{"source":"https://ftp.suse.com/pub/projects/security/osv/SUSE-SU-2018:3776-2.json"}}],"schema_version":"1.7.5"}
