Description

Yahoo! Chat! servers contains a flaw that may allow a remote attacker to bypass 'Add Buddy' restrictions. The problem is that the server does not send confirmation when 'Add Buddy' requests are made. With a specially crafted URL, a remote attacker can arbitrarily add buddies without permission and disclose their online status resulting in a loss of confidentiality.
