All versions of Samba prior to 4.15.5 are vulnerable to a malicious client
using a server symlink to determine if a file or directory exists in an
area of the server file system not exported under the share definition.
SMB1 with unix extensions has to be enabled in order for this attack to
succeed.

|---|---|
| mdeslaur | per upstream, fixing this required a whole rewrite of the VFS layer and there is no reasonable way to fix this in versions older than 4.15.x. Marking this CVE as ignored for older releases. |
