By checking the state of installed package using the pkg audit -F tool on freeBSD 11 , I have found 4 vulnerability on the installed packages (installed through pkg) : samba ,OpenEXR , kdelibs and ImageMagick .

I have upgraded ImageMagick and samba to the latest version ( + following the mitigation guide for samba : adding nt pipe support = no to 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

There is no upgrade available for OpenEXR and kdelibs , the latest version is already installed.

I am using the KDE4 on FreeBSD 11 , the kdelibs vulnerability affect Linux and Unix systems with the KDE4/KDE5 desktop environment.

How to mitigate the multiple vulnerability : remote code execution and local privilege escalation on FreeBSD 11?

  • KDE bug - No mitigation. Update to kauth >= 5.34 and kdelibs >= 4.14.32 (when released) is the solution provided by KDE folks. Just wait for the updated port to have this problem fixed.
  • OpenEXR bugs - No mitigation, and the devs are not showing any sign that they will fix this soon. Best guess here is to remove this package, if you don't really use it (neither is a dependency).
