|CVSS SCORE||9, (AV:N/AC:L/Au:N/C:P/I:P/A:C)|
The specific flaw exists in ATAS32.DLL during the parsing of values defined within the WRF file format. The vulnerable code trusts the linesProcessed value from the file, and uses it in some logic to determine the destination pointer for a memcpy. By supplying an overly large linesProcessed value, the subtraction would cause an integer underflow and allows an attacker control of the destination buffer pointer. This can be further leveraged to execute arbitrary code under the context of the current user.
