Title: Wireshark H.225解析器拒绝服务漏洞

Description:

Wireshark（前称Ethereal）是Wireshark团队开发的一套网络数据包分析软件。该软件的功能是截取网络数据包，并显示出详细的数据以供分析。

Wireshark 2.0.6之前的2.x版本中的H.225解析器中的epan/dissectors/packet-h225.c文件存在拒绝服务漏洞，该漏洞源于程序调用snprintf输入缓冲区作为输出缓冲区。远程攻击者可借助特制的数据包利用该漏洞造成拒绝服务（复制重叠和应用程序崩溃）。

Summary

epan/dissectors/packet-h225.c in the H.225 dissector in Wireshark 2.x before 2.0.6 calls snprintf with one of its input buffers as the output buffer, which allows remote attackers to cause a denial of service (copy overlap and application crash) via a crafted packet.
