CVE: CAN-2005-2307
The Network Connection Manager is used to manage different network connections (e.g. LAN, Dialup ...). A special crafted packet send to a connection can cause the Netowrk Connection Manager to die. However, it will restart once a new request is received.
Not much of a vulnerability. Requires an already authenticated (=connected) user and impact appears to be minimal. The latest versions of Windows are not vulnerable (XP-SP2, Win2k3 SP1). However, older and still popular versions are (like XP-SP1, Win2k3 pre-SP1, Win2k).
Firewall best practices can be used to mitigate the issue.
