Description Huzaifa S. Sidhpurwala 2014-01-22 04:36:26 EST
A Denial-of-Service flaw was found in the way Yahoo protocol plugin handled character encoding. Many places in the Yahoo! protocol plugin assumed incoming strings were UTF-8 and failed to transcode from non-UTF-8 encodings.  This can lead to a crash when receiving strings that aren't UTF-8.
