How the Exploit Works
The vulnerability is triggered when parsing a specially crafted DSB file with Digilent DASYLab. Due to improper bounds checking, an out of bounds write error may occur, resulting in an invalid address. This can potentially allow an attacker to execute arbitrary code. Successful exploitation requires user interaction, specifically a user to open the malicious DSB file.
Conceptual Example Code
The example below is a conceptual representation of a DSB file which might trigger the vulnerability when opened in DASYLab. This is not a real exploit, but an illustration of how an exploit might work.
