Comment 1 Jan Lieskovsky 2012-05-14 12:45:54 UTC
I have tried to test / reproduce this issue on Fedora-15 / Fedora-16 versions (based on ), but unable to reproduce it, because according to aMSN -> Account -> Preferences -> Connection tab -> "File transfer, peer-to-peer and NAT settings" and "Test port" button my connection is: "You are firewalled or behind a router" thus running the ./dos.pl from  returns 'Connection refused' for me. But since there doesn't seem to be an upstream patch for this issue yet, I would say Fedora-15 and Fedora-16 amsn package versions are still vulnerable to this issue. Please schedule an update once there is final upstream patch version available.
