An integer overflow vulnerability exists in the LXT2 lxt2_rd_trace value elements allocation functionality of GTKWave 3.3.115. A specially crafted .lxt2 file can lead to memory corruption. A victim would need to open a malicious file to trigger this vulnerability.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
