Executive brief
DASYLab is a data acquisition and signal analysis software used by engineers and researchers to collect, process, and visualize test data. An out-of-bounds read vulnerability in DSB file parsing allows attackers to craft malicious data files that, when opened by a user, can disclose sensitive information from memory or potentially execute arbitrary code on the affected system.
Technical details
This is an out-of-bounds read vulnerability (CWE-125) in DASYLab's DSB file parser caused by improper validation of user-supplied data. When processing a specially crafted .DSB file, the parser reads beyond the bounds of an allocated data structure, which can leak sensitive information from heap memory or enable code execution. The vulnerability requires user interaction—an attacker must trick a user into opening a malicious DSB file—but the attack is local, not remotely exploitable. The issue affects all DASYLab versions before 2026.0.0 (Build 65), and is resolved in that version and later.
