CVE-2026-1361

A stack-based buffer overflow vulnerability exists in ASDA_Soft version 7.2.0.0 when parsing .par files. The root cause is the improper validation of a user-controlled size parameter, which is checked incorrectly against the upper limits of the local buffer. This allows data to be written past the end of the buffer.
