EulerOS 2.0 SP1 : openssh (EulerOS-SA-2016-1008)
High Nessus Plugin ID 99771
SynopsisThe remote EulerOS host is missing multiple security updates.
DescriptionAccording to the versions of the openssh packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
- 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)
- 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)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
