EulerOS 2.0 SP1 : libssh2 (EulerOS-SA-2016-1005)

medium Nessus Plugin ID 99768

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the version of the libssh2 package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

 - A type confusion issue was found in the way libssh2 generated ephemeral secrets for the diffie-hellman-group1 and diffie-hellman-group14 key exchange methods. This would cause an SSHv2 Diffie-Hellman handshake to use significantly less secure random parameters. (CVE-2016-0787)

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.

Solution

Update the affected libssh2 package.
