Multiple integer underflow vulnerabilities exist in the LXT2 lxt2_rd_iter_radix shift operation 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 these vulnerabilities.This vulnerability concerns the integer underflow when performing the right shift operation.
The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.
