Article ID: 305601 - Last Review: March 29, 2007 - Revision: 8.2 MS01-060: FIX: CRT string format functions may underwrite bufferThis article was previously published under Q305601 On This PageSYMPTOMS Some CRT string format functions may cause an access
violation, stack overflow, or stack corruption due to buffer underwrites.
CAUSE When a printf-style function performs integer or floating-point conversion, it
uses an internal buffer to convert the number into a string. If the
user-supplied Precision property is greater than the internal buffer size, the conversion
writes outside the boundaries of that buffer because the values on the stack
are always the same regardless of the underrun values, and these values cannot
be changed. RESOLUTIONNote All of the hotfixes listed below require you to restart the
computer after installation. Visual C++The Visual C++ 6.0 version of this fix is available at the following Microsoft Developer Network (MSDN) Web site:http://msdn2.microsoft.com/en-us/vstudio/aa718354.aspx
