NVD Description

Note: Versions mentioned in the description apply only to the upstream samba-ad-dc-libs package and not the samba-ad-dc-libs package as distributed by SLES. See How to fix? for SLES:15.3 relevant fixed versions and status.

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.
