FreeBSD <= 6.1 kqueue() NULL pointer dereference
FreeBSD = 6.1 suffers from classical check/use race condition on SMP systems in kevent syscall, leading to kernel mode NULL pointer dereference. It can be triggered by spawning two threads: 1st thread looping on open and close syscalls, and the 2nd thread looping on kevent, trying to add possibly...

Apple Mac OS X KQueue本地拒绝服务漏洞
Apple Mac OS X是一款基于BSD的操作系统。 Apple Mac OS X kqueue和kevent接口处理存在问题，本地攻击者可以利用漏洞对系统进行拒绝服务攻击。 利用一个进程注册一个队列，并通过kevent调用一个内核事件，然后通过fork派生一个子进程，尝试为相同"parent"队列注册另一个事件时可触发漏洞，造成系统拒绝服务。 Apple Mac OS X Server 10.4.8 Apple Mac OS X 10.4.8 http://www.apple.com/macosx/...
