Synopsis
The remote Ubuntu host is missing a security-related patch.
Description
It was discovered that libssh incorrectly handled certain kexinit packets. A remote attacker could possibly use this issue 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.
Solution
Update the affected libssh-4 package.
