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

medium Nessus Plugin ID 28058

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.
