暂无补丁情况
官方补丁披露时间
2019-04-18漏洞描述
在hostapd和wpa_Supplicant中，EAP-PWD的实现容易受到缓存访问模式造成的侧通道攻击。具有EAP-PWD支持的hostapd和wpa_Supplicant的所有版本都是易受攻击的。安装和执行应用程序的能力是成功攻击所必需的。内存访问模式在共享缓存中可见。弱密码可能被破解。hostapd/wpa_Supplicant 2.7及更新版本不会受到CVE-2019-9494中描述的定时攻击的攻击。支持EAP-pwd的hostapd和支持EAP-pwd的wpa_supplicant(包括2.7版本之前)都受到了影响。解决建议
目前厂商已发布升级补丁以修复漏洞，补丁获取链接：https://w1.fi/security/2019-2/eap-pwd-side-channel-attack.txt
