FreeBSD openpty调用访问控制及权限提升漏洞
Vulnerability Description
FreeBSD就是一种运行在Intel平台上、可以自由使用的开放源码Unix类系统。 FreeBSD在处理pty的权限时存在漏洞，本地攻击者可能利用此漏洞提升自己的权限。 FreeBSD的openpty()函数在为打开的伪终端设置权限时存在错误，恶意的本地用户可以通过执行内部调用了openpty()的程序从非root用户所打开的pty读取文本；此外ptsname(3)函数错误的从/dev中的设备节点名获得了两个字符，但没有核实是否操作调用用户所拥有的是有效控制权。pt_chown使用了ptsname(3)
