Description
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences in filenames within Samba client code (libsmbclient). A malicious SMB server can return a filename to the client containing directory traversal characters and force the client to read or write data to local files.
Successful exploitation of the vulnerability may allow an attacker to overwrite arbitrary files on the client.
Remediation
