Gaim is a full featured instant messaging client which handles a variety of instant messaging protocols.
Jacopo Ottaviani discovered a vulnerability in the Yahoo! file transfer code when being offered files with names containing non-ASCII characters (CAN-2005-1269).
Hugo de Bokkenrijder discovered a vulnerability when receiving malformed MSN messages (CAN-2005-1934).
Both vulnerabilities cause Gaim to crash, resulting in a Denial of Service.
There are no known workarounds at this time.
All Gaim users should upgrade to the latest version:
