The _CalcHashValueWithLength function in FastBackServer.exe in the Server in IBM Tivoli Storage Manager (TSM) FastBack 5.5.0.0 through 5.5.6.0 and 6.1.0.0 through 6.1.0.1 does not properly validate an unspecified length value, which allows remote attackers to cause a denial of service (daemon crash) by sending data over TCP. NOTE: this might overlap CVE-2010-3060.
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
