Ubuntu 7.04 : tcp-wrappers vulnerability (USN-507-1)

Ubuntu Security Notice (C) 2007-2016 Canonical, Inc. / NASL script (C) 2007-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

It was discovered that the TCP wrapper library was incorrectly
allowing connections to services that did not specify server-side
connection details. Remote attackers could connect to services that
had been configured to block such connections. This only affected
Ubuntu Feisty.

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 libwrap0, libwrap0-dev and / or tcpd packages.

Risk factor :

Medium / CVSS Base Score : 5.0
(CVSS2#AV:N/AC:L/Au:N/C:P/I:N/A:N)
