Name of the Vulnerable Software and Affected Versions Samba versions 3.x through 4.1.22 Samba versions 4.2.x through 4.2.8 Samba versions 4.3.x through 4.3.5 Samba versions 4.4.x through 4.4.0rc3

Description The issue is related to the implementation of SMB1 in the smbd component of the Samba file system, which is associated with inadequate access control. This allows remote authenticated users to modify arbitrary access control lists (ACLs) by utilizing a UNIX SMB1 call to create a symbolic link, and then using a non-UNIX SMB1 call to write to the ACL content.

Recommendations For Samba versions 3.x, update to version 4.1.23 or later. For Samba versions 4.2.x, update to version 4.2.9 or later. For Samba versions 4.3.x, update to version 4.3.6 or later. For Samba versions 4.4.x, update to version 4.4.0rc4 or later.
