NetBSD项目的Soren Jacobsen今天宣布NetBSD 7.1操作系统系列的第一个版本发布。

在NetBSD 7.1系列发布9个半月之后,NetBSD 7.1.1主要是一个安全性和bug修复版本,解决了四个图形驱动程序通过cmap缓冲区溢出,x86漏洞以及Vnode引用泄漏等重要问题。 openat系统调用。

“NetBSD项目很高兴地宣布NetBSD 7.1.1是NetBSD 7.1发行版的第一个安全/bug修正版本,它代表了一些被认为是安全或稳定性重要的修补程序的子集,如果你运行的是早期版本的NetBSD ,我们强烈建议更新到7.1.1,“阅读今天的公告

下面是NetBSD 7.1.1的新特性

包括在NetBSD 7.1.1中,我们可以找到Heimdal 7.1,BIND 9.10.5-P2,tzdata 2017c,root.cache 2017102400,ntp 4.2.8p10,expat 2.2.1和wpa_supplicant 2.6。 dhcrelay,mtree,ping,resize_ffs,rtadvd,vi和virecover等组件在本版本中也收到了修复程序,您可以在下面看到完整的修改列表。

您也可以学习发行说明,但是NetBSD 7.1.1发行版中包含的大部分更改都位于内核中,针对与ipfilter,netsmb,vnd,dm9000,cgd,bwi等组件相关的各种问题, altq,compat_svr4,compat_linux,evbmips,i82596,ipw,isp,ural,wm等。

这不是一个主要的版本,但是如果它为初始的NetBSD 7.1安装增加了一层额外的稳定性和安全性改进,那么这个版本是非常值得欢迎的。因此,我们建议所有的NetBSD 7.1用户尽快升级到7.1.1版本,对于新的部署,你可以从我们的网站上下载NetBSD 7.1.1 ISO映像
