Out Of Bounds Write when parsing a .DSB file in DASYLab due to improper validation of user-supplied data, resulting in a write past the end of an allocated heap

There is an out-of-bounds write vulnerability in DASYLab due to improper validation of user-supplied data, resulting in a write past the end of an allocated heap. Successful exploitation requires an attacker to get a user to open a specially crafted .DSB file.  This issue affects all versions before 2026.0.0.
