Ubuntu Security Notice (C) 2014-2016 Canonical, Inc. / NASL script (C) 2014-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Ryan Finnie discovered that the rsync daemon incorrectly handled
invalid usernames. A remote attacker could use this issue to cause
rsync to consume resources, 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 rsync package.
