pptpd vulnerability



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.

The problem can be corrected by updating your system to the following package versions:

Ubuntu 7.04
  • pptpd - 1.3.0-2ubuntu2.1
Ubuntu 6.10
  • pptpd - 1.3.0-1ubuntu1.1
Ubuntu 6.06
  • pptpd - 1.2.3-1ubuntu0.1

necessary changes.
