Red Hat Product Errata RHSA-2014:0139 0 normal SHIPPED_LIVE Moderate: pidgin security update 2014-02-05 22:42:24 UTC

Description Huzaifa S. Sidhpurwala 2014-01-22 09:36:26 UTC 
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.
