Ubuntu 6.06 LTS : pptpd vulnerabilities (USN-459-2)

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 :

USN-459-1 fixed vulnerabilities in pptpd. However, a portion of the
fix caused a regression in session establishment under Dapper for
certain PPTP clients. This update fixes the problem.

We apologize for the inconvenience.

A flaw was discovered in the PPTP tunnel server. Remote attackers
could send a specially crafted packet and disrupt established PPTP
tunnels, leading to 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 bcrelay and / or pptpd packages.

Risk factor :

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