Dell BIOS versions contain a Stack-based Buffer Overflow vulnerability. A local authenticated malicious user could potentially exploit this vulnerability by sending excess data to a function in order to gain arbitrary code execution on the system.
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
The product writes data past the end, or before the beginning, of the intended buffer.
