FreeBSD 10.2 64位内核堆溢出漏洞（CVE-2016-1885）

FreeBSD简介 FreeBSD是一种类UNIX的开源操作系统，为不同架构的计算机系统提供了不同程度的支持。FreeBSD提供先进的网络、性能、安全以及兼容性，这些特性在其他现代操作系统上仍有所缺失，即使是一些最好的商业操作系统。 在网络方面，FreeBSD的性能也是相当优异的。在很重的负载之下，FreeBSD仍然可以稳定的运行，这也是很多网络服务器采用 FreeBSD 的原因之一。 漏洞描述 在FreeBSD...

FreeBSD 远程拒绝服务攻击漏洞

0x01 漏洞复现 此漏洞是由于FreeBSD在处理ipv6数据包时，某函数对于数据的检验不严格，导致若传入的ipv6结构体某成员函数为NULL时，在后续函数调用中会触发assert，导致freebsd进入异常处理机制，内核崩溃引发系统重启，下面对此漏洞进行详细分析。 首先对于漏洞环境的搭建我不讲解了，在我的微信公众号上发了一篇文章专门讲解FreeBSD环境的搭建，包括内核调试，vmtools安装等等，环境搭建好之后，通过执行poc.py，发现程序重启，重启过程中，/var/crash下会生成崩溃信息。...
