Please note that due to a bug in the previous shipped openssh version,
sshd might not correctly restart. Please verify that the ssh daemon is
running after installing this update.
These security issues were fixed :
- CVE-2015-5352: The x11_open_helper function, when
ForwardX11Trusted mode is not used, lacked a check of
the refusal deadline for X connections, which made it
easier for remote attackers to bypass intended access
restrictions via a connection outside of the permitted
time window. (bsc#936695)
- CVE-2015-5600: The kbdint_next_device function in
auth2-chall.c in sshd did not properly restrict the
processing of keyboard-interactive devices within a
single connection, which made 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. (bsc#938746)
- CVE-2015-4000: Removed and disabled weak DH groups to
address LOGJAM. (bsc#932483)
- Hardening patch to fix sftp RCE. (bsc#903649)
- CVE-2015-6563: The monitor component in sshd accepted
extraneous username data in MONITOR_REQ_PAM_INIT_CTX
requests, which allowed local users to conduct
impersonation attacks by leveraging any SSH login access
in conjunction with control of the sshd uid to send a
crafted MONITOR_REQ_PWNAM request, related to monitor.c
and monitor_wrap.c.
- CVE-2015-6564: Use-after-free vulnerability in the
mm_answer_pam_free_ctx function in monitor.c in sshd
might have allowed local users to gain privileges by
leveraging control of the sshd uid to send an
unexpectedly early MONITOR_REQ_PAM_FREE_CTX request.
Additional a bug was fixed that could lead to openssh not working in
chroot (bsc#947458).
Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
