A stack-based buffer overflow has been found in conv_euctojis() after applying incomplete patch for CVE-2015-8614. In conv_euctojis() the comparison is with outlen - 3, but each pass through the loop uses up to 5 bytes and the rest of the function may add another 4 bytes. The comparison should presumably be '<= outlen - 9' or equivalently '< outlen - 8'. CVE assignment: http://www.openwall.com/lists/oss-security/2015/12/31/3
