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.

Solution :

Update the affected bcrelay and / or pptpd packages.

Risk factor :

Medium / CVSS Base Score : 5.0
