OVERVIEW

        IBM have released fixes for a number of vulnerabilities in IBM
        Tivoli Storage Manager Client.


IMPACT

        The vendor has provided the following information regarding these
        vulnerabilities [1]:
        
        CAD Scheduler Buffer Overrun:
        A buffer overrun vulnerability exists in the client acceptor daemon 
        (CAD) scheduler, which has the potential to crash the TSM client 
        agent process or to allow malicious code injection. The malicious 
        code could, for example, allow an unauthorized user to read, copy, 
        alter, or delete files on the client machine.
        
        Traditional Scheduler Buffer Overrun:
        A buffer overrun vulnerability exists in the traditional client 
        scheduler, which has the potential to crash the TSM client or to 
        allow malicious code injection. The malicious code could, for 
        example, allow an unauthorized user to read, copy, alter, or delete 
        files on the client machine.
        
        Unauthorized Access with MAILPROG option:
        An unauthorized access vulnerability exists in the UNIX and Linux 
        backup-archive clients and the OS/400 API client when the MAILPROG 
        option is specified. The vulnerability could, for example, allow an 
        unauthorized user to read, copy, alter, or delete files on the client 
        machine.


MITIGATION

        Fixes have been released for the affected version of Tivoli Storage 
        Manager Client. Please see the vendor's advisory [1] for the 
        download link for your specific version.
