Description Jan Lieskovsky 2011-03-08 11:52:52 UTC

Multiple NULL pointer dereference flaws were found in the way Yahoo protocol
plug-in of the Pidgin instant messaging client handled malformed YMSG packets
(SMS messages and notification packets). A remote, authenticated user could
use this flaw to cause denial of service (Pidgin crash) via specially-crafted
notification message. The SMS messages handling issue is exploitable only via
specially-crafted SMS message, sent from remote, malicious Yahoo server.

Acknowledgements:
