如何緩解多重漏洞:FreeBSD 11 上的遠端程式碼執行和本地權限提升?
通過使用 freeBSD 11 上的工具檢查已安裝包的狀態,
pkg audit -F
我發現已安裝包(通過 安裝pkg
)上存在 4 個漏洞:samba
、OpenEXR
和.kdelibs``ImageMagick
我已經升級
ImageMagick
到samba
最新版本(+ 遵循samba緩解指南:添加nt pipe support = no
到nsmb.conf
)。#pkg search samba p5-Samba-LDAP-0.05_2 Manage a Samba PDC with an LDAP Backend p5-Samba-SIDhelper-0.0.0_3 Create SIDs based on G/UIDs samba-nsupdate-9.8.6_1 nsupdate utility with GSS-TSIG support samba42-4.2.14_1 Free SMB/CIFS and AD/DC server and client for Unix samba43-4.3.13_2 Free SMB/CIFS and AD/DC server and client for Unix samba44-4.4.13 Free SMB/CIFS and AD/DC server and client for Unix samba45-4.5.8 Free SMB/CIFS and AD/DC server and client for Unix samba46-4.6.2 Free SMB/CIFS and AD/DC server and client for Unix
OpenEXR
和沒有可用的升級kdelibs
,已安裝最新版本。我在 FreeBSD 11 上使用 KDE4,該
kdelibs
漏洞影響具有 KDE4/KDE5 桌面環境的 Linux 和 Unix 系統。如何緩解多重漏洞:FreeBSD 11 上的遠端程式碼執行和本地權限提升?
