The specific flaws exists during the parsing of messages with overly
long attribute values within the FONT tag. The value for any attribute
is copied into a stack based buffer via sprintf() which can result in a
buffer overrun and can be subsequently leveraged to execute arbitrary
code under the privileges of the logged in user. Exploitation may occur
over the AIM network or via direct connections.
