New! Plugin Severity Now Using CVSS v3

Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for openssh fixes the following issues :

- CVE-2016-0777: A malicious or compromised server could cause the OpenSSH client to expose part or all of the client's private key through the roaming feature (bsc#961642)

- CVE-2016-0778: A malicious or compromised server could could trigger a buffer overflow in the OpenSSH client through the roaming feature (bsc#961645)

This update disables the undocumented feature supported by the OpenSSH client and a commercial SSH server.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
