Bug 113846

A number of vulnerabilities in GAIM found by Stefan Esser.
Notified to vendor-sec on Jan16th and have been committed to CVS. 
Agreed to hold off on disclosure of the details until Stefan has sent
his advisory.

Due to the nature of instant messaging many of these bugs
require man-in-the-middle attacks between client and server.
However at least one of the buffer overflows could be exploited
by an attacker sending a carefully constructed malicious
message through a server.

cookies in a Yahoo web connection, YMSG protocol overflows
parsing Yahoo Login Webpage, YMSG packet overflow, URL parser,
