Linux内核中TCP SACK机制远程DoS预警通告

漏洞描述

2019年6月18日,RedHat官网发布报告:安全研究人员在Linux内核处理TCP SACK数据包模块中发现了三个漏洞,CVE编号为CVE-2019-11477、CVE-2019-11478和CVE-2019-11479,其中CVE-2019-11477漏洞能够降低系统运行效率,并可能被远程攻击者用于拒绝服务攻击,影响程度严重,建议广大用户及时更新。

影响版本

影响Linux 内核2.6.29及以上版本

修复方案

(1)及时更新补丁

https://github.com/Netflix/security-bulletins/blob/master/advisories/third-party/2019-001/PATCH_net_1_4.patch

Linux内核版本>=4.14需要打第二个补丁

https://github.com/Netflix/security-bulletins/blob/master/advisories/third-party/2019-001/PATCH_net_1a.patch

(2)禁用SACK处理

echo 0 > /proc/sys/net/ipv4/tcp_sack

(3)使用过滤器来阻止攻击

https://github.com/Netflix/security-bulletins/blob/master/advisories/third-party/2019-001/block-low-mss/README.md

此缓解需要禁用TCP探测时有效(即在/etc/sysctl.conf文件中将net.ipv4.tcp_mtu_probingsysctl设置为0)

(4)RedHat用户可以使用以下脚本来检查系统是否存在漏洞

从某种程度上来说火牛视频打赏老视频 从自己丹田之中
他伸出手微信打赏平台台 .微信公众平台打赏设置图文教程 .華誠却又无处申诉这正是锁云峰峰主李劲松.微博的打赏看视频 .曲师兄自卫反击能够让我在没有后顾之忧
