REDHAT-BUG-683031: Null Pointer Dereference
First published: Tue Mar 08 2011(Updated: )
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: Red Hat would like to thank the Pidgin project for reporting these issues. Upstream acknowledges Marius Wachtler as the original reporter.
