FreeBSD -- kqueue pipe race conditions
Problem Description A race condition exists in the pipe close code relating to kqueues, causing use-after-free for kernel memory, which may lead to an exploitable NULL pointer vulnerability in the kernel, kernel memory corruption, and other unpredictable results. Impact: Successful exploitation o...

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/...
