https://notcve.org/view.php?id=CVE-2016-3116
CRLF injection vulnerability in Dropbear SSH before 2016.72 allows remote authenticated users to bypass intended shell-command restrictions via crafted X11 forwarding data. Vulnerabilidad de inyección CRLF en Dropbear SSH en versiones anteriores a 2016.72 permite a usuarios remotos autenticados eludir las restricciones de comandos de shell previstas a través del redireccionamiento de datos X11 manipulados. Dropbear sshd versions 2015.71 and below suffer from a command injection vulnerability via xauth. An authenticated user may inject arbitrary xauth commands by sending an x11 channel request that includes a newline character in the x11 cookie. The newline acts as a command separator to the xauth binary. • https://www.exploit-db.com/exploits/40119 https://github.com/mxypoo/CVE-2016-3116-DropbearSSH http://lists.fedoraproject.org/pipermail/package-announce/2016-March/179261.html http://lists.fedoraproject.org/pipermail/package-announce/2016-March/179269.html http://lists.fedoraproject.org/pipermail/package-announce/2016-March/179870.html http://lists.opensuse.org/opensuse-updates/2016-03/msg00105.html http://lists.opensuse.org/opensuse-updates/2016-03/msg00113.html http://packetstormsecurity.com/files/1362 •
