nasm is vulnerable to Denial of Service (DoS) attacks. The vulnerability exists in the ieee_segment function in the outieee.c file. The function is responsible for writing floating-point numbers to an output file. The vulnerability occurs when the function fails to properly check the size of the buffer that is used to store the floating-point number. This can cause the function to access memory that it is not supposed to access, resulting in a segmentation fault.
