Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

negotiation requests. A remote attacker could use this to cause libssh
to crash, resulting in a denial of service.

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