Vulnerability Title
Hanterm-XF基于循环的转义序列拒绝服务漏洞
Vulnerability Description
转义序列(escape sequence)是一系列由ASCII转义字符(0x1B)开始的字符序列，并附带特殊的参数构成，转义序列一般原用于控制显示设备如终端，现在扩展在大多数操作系统中允许多种形式的交互。转义序列可以用于更改文本属性(颜色，宽度)，移动鼠标位置，重配置键盘，更新窗口标题，或者操作打印机等。 hanterm-xf终端模拟器不正确过滤部分恶意基于循环的转义序列，本地攻击者可以利用这个漏洞消耗系统大量CPU资源而产生拒绝服务。 当由DEC UDK处理器实现的模拟终端不充分处理基于循环的转义序列符
