The SASspk module (SASspk.dll) version 9.310.0.11307, has a function called 'RetrieveBinaryFile()' which has one parameter called 'bstrFileName' which takes arguments as strings as defined in the function itself as ISPKBinaryFile from the SASPackageRetrieve library. Stack-based buffer overflow was discovered in one of the fuzzing processes that could allow arbitrary code execution by an attacker when exploiting the non-sanitized 'bstrFileName' parameter.
