Título:	OpenSSH <= 7.2p1 Xauth Command Injection Vulnerability
Resumen:	OpenSSH is prone to an xauth command injection vulnerability.
Descripción:	Summary: OpenSSH is prone to an xauth command injection vulnerability. Vulnerability Insight: 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. This attack requires the server to have 'X11Forwarding yes' enabled. Disabling it, mitigates this vector. Vulnerability Impact: By injecting xauth commands one gains limited* read/write arbitrary files, information leakage or xauth-connect capabilities. Affected Software/OS: OpenSSH versions before 7.2p2. Solution: Update to version 7.2p2 or later. CVSS Score: 5.5 CVSS Vector: AV:N/AC:L/Au:S/C:P/I:P/A:N
