Details

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.

Original advisory details:

A flaw was discovered in the PPTP tunnel server. Remote attackers could
send a specially crafted packet and disrupt established PPTP tunnels,
