通过使用 freeBSD 11 上的工具检查已安装软件包的状态pkg audit -F
,我在已安装软件包(通过安装pkg
)上发现了 4 个漏洞:samba
、OpenEXR
、kdelibs
和ImageMagick
。
我已经升级 ImageMagick
到samba
最新版本(+遵循缓解指南对于桑巴舞: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
和没有可用的升级kdelibs
,已安装最新版本。
我在 FreeBSD 11 上使用 KDE4,该kdelibs
漏洞影响具有 KDE4/KDE5 桌面环境的 Linux 和 Unix 系统。
如何缓解 FreeBSD 11 上的多个漏洞:远程代码执行和本地权限提升?
