Scientific Linux Security Update : openssh on SL7.x x86_64
High Nessus Plugin ID 90081
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionIt 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)
An access flaw was discovered in OpenSSH; the OpenSSH client did not correctly handle failures to generate authentication cookies for untrusted X11 forwarding. A malicious or compromised remote X application could possibly use this flaw to establish a trusted connection to the local X server, even if only untrusted X11 forwarding was requested. (CVE-2016-1908)
After installing this update, the OpenSSH server daemon (sshd) will be restarted automatically.
SolutionUpdate the affected packages.
