This problem was reontroduced by another patch and was previously fixed by another update (bsc#1069509). These non-security issues were fixed: - Remove duplicate KEX method (bsc#1053972) - New switch for printing diagnostic messages in sftp client's batch mode (bsc#1023275) - Enable case-insensitive hostname matching (bsc#1017099) The CVRF data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0). secsp3-openssh-openssl1-13777 Copyright SUSE LLC under the Creative Commons License 4.0 with Attribution (CC-BY-4.0) https://www.suse.com/support/update/announcement/2018/suse-su-20182719-1/ Link for SUSE-SU-2018:2719-1 https://lists.suse.com/pipermail/sle-security-updates/2018-September/004564.html E-Mail link for SUSE-SU-2018:2719-1 https://www.suse.com/support/security/rating/ SUSE Security Ratings https://bugzilla.suse.com/1016370 SUSE Bug 1016370 https://bugzilla.suse.com/1017099 SUSE Bug 1017099 https://bugzilla.suse.com/1023275 SUSE Bug 1023275 https://bugzilla.suse.com/1053972 SUSE Bug 1053972 https://bugzilla.suse.com/1065000 SUSE Bug 1065000 https://bugzilla.suse.com/1069509 SUSE Bug 1069509 https://bugzilla.suse.com/1076957 SUSE Bug 1076957 https://www.suse.com/security/cve/CVE-2008-1483/ SUSE CVE CVE-2008-1483 page https://www.suse.com/security/cve/CVE-2016-10012/ SUSE CVE CVE-2016-10012 page https://www.suse.com/security/cve/CVE-2016-10708/ SUSE CVE CVE-2016-10708 page https://www.suse.com/security/cve/CVE-2017-15906/ SUSE CVE CVE-2017-15906 page SUSE Linux Enterprise Server 11-SECURITY openssh-openssl1-6.6p1-19.3.1 openssh-openssl1-helpers-6.6p1-19.3.1 openssh-openssl1-6.6p1-19.3.1 as a component of SUSE Linux Enterprise Server 11-SECURITY openssh-openssl1-helpers-6.6p1-19.3.1 as a component of SUSE Linux Enterprise Server 11-SECURITY OpenSSH 4.3p2, and probably other versions, allows local users to hijack forwarded X connections by causing ssh to set DISPLAY to :10, even when another process is listening on the associated port, as demonstrated by opening TCP port 6010 (IPv4) and sniffing a cookie sent by Emacs.
