"The version of IBM Tivoli Storage Manager FastBack running on the
remote host is 6.1.x prior to 6.1.11.1. It is, therefore, affected by
multiple vulnerabilities :

  - A flaw exists in the mount service due to improper
    validation of user-supplied input to the
    CRYPTO_S_EncryptBufferToBuffer() function. A remote,
    unauthenticated attacker can exploit this flaw, via
    a series of specially crafted packets, to cause a
    stack-based buffer overflow, resulting in a denial of
    service condition or the execution of arbitrary code.
    (CVE-2015-0120)
    
  - An overflow condition exists in the mount service due to
    improper bounds checking. A remote, unauthenticated 
    attacker can exploit this to cause a stack-based buffer
    overflow, resulting in a denial of service condition
    or the execution of arbitrary code. (CVE-2015-1896)
