Description

A weakness has been reported in MLDonkey, which can be exploited by malicious people to bypass certain security restrictions.

The weakness is caused due to MLDonkey loading "$MLDONKEY/web_infos/*" after activating the network modules. This may allow other peers to connect from blocked IP addresses for a short time span.

The weakness is reported in versions prior to 2.9.0.
