-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: openssh security, bug fix, and enhancement update Advisory ID: RHSA-2016:2588-02 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-2588.html Issue date: 2016-11-03 CVE Names: CVE-2015-8325 ===================================================================== 1. Summary: An update for openssh is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client (v. 7) - x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64 3. Description: OpenSSH is an SSH protocol implementation supported by a number of Linux, UNIX, and similar operating systems. It includes the core files necessary for both the OpenSSH client and server. Security Fix(es): * It was discovered that the OpenSSH sshd daemon fetched PAM environment settings before running the login program. In configurations with UseLogin=yes and the pam_env PAM module configured to read user environment settings, a local user could use this flaw to execute arbitrary code as root. (CVE-2015-8325) Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.3 Release Notes linked from the References section. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 After installing this update, the OpenSSH server daemon (sshd) will be restarted automatically. 5. Bugs fixed (https://bugzilla.redhat.com/): 1237129 - sshd -T does not output authenticationmethods with default value 1291172 - systemctl restart/start sshd shows no error if start fails 1310303 - remove GLOB_LIMIT_STAT from OpenSSH 1312013 - rhpkg prep fails on rhel-7.3 branch 1328012 - CVE-2015-8325 openssh: privilege escalation via user's PAM environment and UseLogin=yes 1328243 - OpenSSH only looks for .k5login in user directory 1344614 - sftp -m modifies umask and breaks permissions on new directories 1349556 - ssh-copy-id not working when custom loglevel is quiet 1357859 - guest_t can run sudo 1373297 - openssh can't be installed without selinux-policy 6.
