"The version of IBM Tivoli Storage Manager FastBack running on the
remote host is 6.1.x prior to 6.1.12. It is, therefore, affected by
multiple vulnerabilities :

  - An overflow condition exists due to improper validation
    of user-supplied input when handling opcode 1331. A
    remote, unauthenticated attacker can exploit this issue
    to cause a buffer overflow, resulting in a denial of
    service condition or the execution of arbitrary code.
    (CVE-2015-1923)

  - An overflow condition exists due to improper validation
    of user-supplied input when handling opcode 1329. A
    remote, unauthenticated attacker can exploit this issue
    to cause a stack-based buffer overflow, resulting in a
    denial of service condition or the execution of
    arbitrary code. (CVE-2015-1924)

  - An overflow condition exists due to improper validation
    of user-supplied input when handling opcode 1332. A
    remote, unauthenticated attacker can exploit this issue
    to cause an overflow, resulting in a denial of service
    condition or the execution of arbitrary code.
    (CVE-2015-1925)

  - A buffer overflow condition exists in the
    FXCLI_OraBR_Exec_Command() function due to improper
    validation of user-supplied input. A remote,
    unauthenticated attacker can exploit this issue, via a
    specially crafted packet, to cause a stack-based buffer
    overflow, resulting in a denial of service or the
    execution of arbitrary code. (CVE-2015-1929)

  - A buffer overflow condition exists in the
    JOB_S_GetJobByUserFriendlyString() function due to
    improper validation of user-supplied input. A remote,
    unauthenticated attacker can exploit this issue, via a
    specially crafted packet, to cause a stack-based buffer
    overflow, resulting in a denial of service or the
    execution of arbitrary code. (CVE-2015-1930)

  - An overflow condition exists due to improper validation
    of user-supplied input when handling opcode 1331. A
    remote, unauthenticated attacker can exploit this issue,
    via a specially crafted packet, to execute arbitrary
    commands with a system call. (CVE-2015-1938)

  - An unspecified flaw exists that occurs during the
    handling of opcode 1329. A remote, unauthenticated
    attacker can exploit this issue to gain access to
    arbitrary files. (CVE-2015-1941)

  - An unspecified flaw exists that occurs during the
    handling of opcode 1332. A remote, unauthenticated
    attacker can exploit this issue to write or execute
    arbitrary files. (CVE-2015-1942)

  - An overflow condition exists due to improper validation
    of user-supplied input when handling opcode 1364. A
    remote, unauthenticated attacker can exploit this
    issue, via a specially crafted packet, to cause a
    stack-based buffer overflow, resulting in a denial of
    service condition or the execution of arbitrary code.
    (CVE-2015-1948)

  - An unspecified flaw exists that is triggered during the
    handling of opcode 1330. A remote, unauthenticated
    attacker can exploit this issue, via specially crafted
    packet, to execute arbitrary commands with a system
    call. (CVE-2015-1949)

  - A format string flaw exists in the vsprintf() function
    due to improper sanitization of user-supplied format
    string specifiers when processing opcode 1335. A remote,
    unauthenticated attacker can exploit this issue, via a
    specially crafted packet, to cause a denial of service
    condition or the execution of arbitrary code.
    (CVE-2015-1953)

  - An overflow condition exists due to improper validation
    of user-supplied input. A remote, unauthenticated
    attacker can exploit this issue to cause a stack-based
    buffer overflow, resulting in a denial of service
    condition or the execution of arbitrary code.
    (CVE-2015-1954)

  - An overflow condition exists due to improper validation
    of user-supplied input. A remote, unauthenticated
    attacker can exploit this issue to cause a stack-based
    buffer overflow, resulting in a denial of service
    condition or the execution of arbitrary code.
    (CVE-2015-1962)

  - An overflow condition exists due to improper validation
    of user-supplied input. A remote, unauthenticated
    attacker can exploit this issue to cause a stack-based
    buffer overflow, resulting in a denial of service
    condition or the execution of arbitrary code.
    (CVE-2015-1963)

  - An overflow condition exists due to improper validation
    of user-supplied input. A remote, unauthenticated
    attacker can exploit this issue to cause a stack-based
    buffer overflow, resulting in a denial of service
    condition or the execution of arbitrary code.
    (CVE-2015-1964)

  - An overflow condition exists due to improper validation
    of user-supplied input. A remote, unauthenticated
    attacker can exploit this issue to cause a stack-based
    buffer overflow, resulting in a denial of service
    condition or the execution of arbitrary code.
    (CVE-2015-1965)

  - A format string flaw exists in the vsprintf() function
    due to improper sanitization of user-supplied format
    string specifiers when processing opcode 1301. A remote,
    unauthenticated attacker can exploit this issue, via a
    specially crafted packet, to cause a denial of service
    condition or the execution of arbitrary code.
    (CVE-2015-1986)

  - Multiple stack-based buffer overflow conditions exist
    due to improper bounds checking. A remote attacker can
    exploit these, via a crafted packet, to crash the server
    or execute arbitrary code with SYSTEM privileges.
