These security issues were fixed: - CVE-2016-3115: Multiple CRLF injection vulnerabilities in session.c in sshd in OpenSSH allowed remote authenticated users to bypass intended shell-command restrictions via crafted X11 forwarding data, related to the (1) do_authenticated1 and (2) session_x11_req functions (bsc#970632). - CVE-2016-1908: Possible fallback from untrusted to trusted X11 forwarding (bsc#962313). - CVE-2015-8325: Ignore PAM environment vars when UseLogin=yes (bsc#975865). These non-security issues were fixed: - Correctly parse GSSAPI KEX algorithms (bsc#961368) - More verbose FIPS mode/CC related documentation in README.FIPS (bsc#965576, bsc#960414) - Fix PRNG re-seeding (bsc#960414, bsc#729190) - Disable DH parameters under 2048 bits by default and allow lowering the limit back to the RFC 4419 specified minimum through an option (bsc#932483, bsc#948902) - Allow empty Match blocks (bsc#961494) The CVRF data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0). slessp4-openssh-12603 Copyright SUSE LLC under the Creative Commons License 4.0 with Attribution (CC-BY-4.0) https://www.suse.com/support/update/announcement/2016/suse-su-20161528-1/ Link for SUSE-SU-2016:1528-1 https://lists.suse.com/pipermail/sle-security-updates/2016-June/002103.html E-Mail link for SUSE-SU-2016:1528-1 https://www.suse.com/support/security/rating/ SUSE Security Ratings https://bugzilla.suse.com/729190 SUSE Bug 729190 https://bugzilla.suse.com/932483 SUSE Bug 932483 https://bugzilla.suse.com/948902 SUSE Bug 948902 https://bugzilla.suse.com/960414 SUSE Bug 960414 https://bugzilla.suse.com/961368 SUSE Bug 961368 https://bugzilla.suse.com/961494 SUSE Bug 961494 https://bugzilla.suse.com/962313 SUSE Bug 962313 https://bugzilla.suse.com/965576 SUSE Bug 965576 https://bugzilla.suse.com/970632 SUSE Bug 970632 https://bugzilla.suse.com/975865 SUSE Bug 975865 https://www.suse.com/security/cve/CVE-2015-8325/ SUSE CVE CVE-2015-8325 page https://www.suse.com/security/cve/CVE-2016-1908/ SUSE CVE CVE-2016-1908 page https://www.suse.com/security/cve/CVE-2016-3115/ SUSE CVE CVE-2016-3115 page SUSE Linux Enterprise Server 11 SP4 SUSE Linux Enterprise Server for SAP Applications 11 SP4 openssh-6.6p1-21.1 openssh-askpass-gnome-6.6p1-21.3 openssh-fips-6.6p1-21.1 openssh-helpers-6.6p1-21.1 openssh-6.6p1-21.1 as a component of SUSE Linux Enterprise Server 11 SP4 openssh-askpass-gnome-6.6p1-21.3 as a component of SUSE Linux Enterprise Server 11 SP4 openssh-fips-6.6p1-21.1 as a component of SUSE Linux Enterprise Server 11 SP4 openssh-helpers-6.6p1-21.1 as a component of SUSE Linux Enterprise Server 11 SP4 openssh-6.6p1-21.1 as a component of SUSE Linux Enterprise Server for SAP Applications 11 SP4 openssh-askpass-gnome-6.6p1-21.3 as a component of SUSE Linux Enterprise Server for SAP Applications 11 SP4 openssh-fips-6.6p1-21.1 as a component of SUSE Linux Enterprise Server for SAP Applications 11 SP4 openssh-helpers-6.6p1-21.1 as a component of SUSE Linux Enterprise Server for SAP Applications 11 SP4 The do_setup_env function in session.c in sshd in OpenSSH through 7.2p2, when the UseLogin feature is enabled and PAM is configured to read .pam_environment files in user home directories, allows local users to gain privileges by triggering a crafted environment for the /bin/login program, as demonstrated by an LD_PRELOAD environment variable.
