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.
Buffer overflows in Gaim 0.75 and earlier including parsing
cookies in a Yahoo web connection, YMSG protocol overflows
parsing Yahoo Login Webpage, YMSG packet overflow, URL parser,
and HTTP Proxy connect.
Buffer overflow in Gaim 0.74 and earlier in the Extract Info
Field Function used for MSN and YMSG protocol handlers.
Integer Overflow in Gaim 0.74 and earlier, when allocating
memory for a directIM packet results in heap overflow.
Removing embargo. Issue public 10am CET on Jan26 to full-disclosure
list by Stefan
