The vulnerability of the OpenBSD operating system, which allows a hacker to trigger a service failure
The vulnerability of the OpenBSD operating system is related to errors in number processing. Exploiting this vulnerability allows a malicious actor, operating locally, to cause a service failure—i.e., the appearance of a “Assertion failure” window and a kernel error. This occurs by using a large...

CVE-2016-6242
OpenBSD 5.8 and 5.9 are affected by CVE-2016-6242: a local attacker can trigger a denial of service by supplying a large ident value to a kevent system call, causing an assertion failure and kernel panic. This is a local-privilege context with no remote access implied. The observed impact is a ke...

FreeBSD kevent()系统调用竞争条件漏洞
BUGTRAQ ID: 36101 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的SMP系统中的kevent系统调用存在竞争条件错误。如果本地用户生成了两个线程，其中第一个线程循环执行open和close系统调用而第二个线程循环执行kevent尝试添加无效的文件描述符，就会触发内核态的空指针引用，导致拒绝服务或运行root shell。 FreeBSD = 6.1 厂商补丁： FreeBSD ------- 目前厂商已经发布了升级补丁以修复这个安全问题，请到厂商的主页下载：...
