Título:	RedHat Update for openssh RHSA-2016:0466-01
Resumen:	The remote host is missing an update for the 'openssh'; package(s) announced via the referenced advisory.
Descripción:	Summary: The remote host is missing an update for the 'openssh' package(s) announced via the referenced advisory. Vulnerability Insight: OpenSSH is OpenBSD's SSH (Secure Shell) protocol implementation. These packages include the core files necessary for both the OpenSSH client and server. It was discovered that the OpenSSH server did not sanitize data received in requests to enable X11 forwarding. An authenticated client with restricted SSH access could possibly use this flaw to bypass intended restrictions. (CVE-2016-3115) It was discovered that the OpenSSH sshd daemon did not check the list of keyboard-interactive authentication methods for duplicates. A remote attacker could use this flaw to bypass the MaxAuthTries limit, making it easier to perform password guessing attacks. (CVE-2015-5600) All openssh users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, the OpenSSH server daemon (sshd) will be restarted automatically. Affected Software/OS: openssh on Red Hat Enterprise Linux Desktop (v. 6), Red Hat Enterprise Linux Server (v. 6), Red Hat Enterprise Linux Workstation (v. 6) Solution: Please Install the Updated Packages. CVSS Score: 8.5 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:N/A:C
