The client in IBM Tivoli Storage Manager (TSM) 6.3.1 and 6.4.0 on Windows does not preserve permissions of Resilient File System (ReFS) files across backup and restore operations, which allows local users to bypass intended access restrictions via standard filesystem operations.

The server in IBM Tivoli Storage Manager (TSM) 5.x and 6.x before 6.3.5.10 and 7.x before 7.1.1.100 allows remote attackers to bypass intended access restrictions and replace file backups by using a certain backup option in conjunction with a filename that matches a previously used filename.

IBM Spectrum Protect (formerly Tivoli Storage Manager) 5.5 through 6.3 before 6.3.2.6, 6.4 before 6.4.3.3, and 7.1 before 7.1.6 allows local users to obtain sensitive retrieved data from arbitrary accounts in opportunistic circumstances by leveraging previous use of a symlink during archive and retrieve actions.
