CVE-2025-57775
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThere is a heap-based Buffer Overflow vulnerability due to improper bounds checking when parsing a DSB file with Digilent DASYLab. This vulnerability may result in arbitrary code execution. Successful exploitation requires an attacker to get a user to open a specially crafted DSB file. The vulnerability affects all versions of DASYLab.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA heap-based buffer overflow vulnerability exists in Digilent DASYLab's DSB file parser due to improper bounds checking during file parsing. An attacker can exploit this by tricking a user into opening a specially crafted DSB file, potentially achieving arbitrary code execution with the user's privileges.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify DASYLab installationCheck for DASYLab installation directory (commonly at C:\Program Files\DASYLab or C:\Program Files (x86)\DASYLab). On Windows, open Programs and Features and look for 'DASYLab' or 'Ni Dasylab'.Affected if DASYLab is installed on the system
-
Confirm DSB file handler existsLocate the DSB parsing module or DLL within the DASYLab installation directory. Look for files named dasylab.exe or supporting DLLs that handle .dsb file format parsing.Affected if The DSB file parser module is present in the DASYLab installation
-
Check for DSB file associationsOpen Windows Registry and check for .dsb file association under HKEY_CLASSES_ROOT\.dsb or verify if DASYLab is set as the default handler for .dsb files.Affected if DSB files are associated with DASYLab as the default opener
-
Verify DSB import functionalityLaunch DASYLab and check if the DSB file import/parse feature is available or enabled. This may appear as a driver, module, or import option within the application.Affected if DSB file import or parsing functionality is present and enabled in DASYLab
If DASYLab (Ni Dasylab) is installed with DSB file parsing capabilities enabled, the environment is affected by this vulnerability when processing untrusted DSB files.
