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 · unedited
Stack overflow in custom XML-parser in Gemalto's HASP SRM, Sentinel HASP and Sentinel LDK products prior to Sentinel LDK RTE version 7.55 leads to remote denial of service.

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 · moderate confidence

A stack overflow vulnerability exists in the custom XML-parser of Gemalto's HASP SRM, Sentinel HASP, and Sentinel LDK products prior to Sentinel LDK RTE version 7.55. The vulnerability can be exploited remotely by sending specially crafted XML input to the parser, causing a stack overflow that leads to denial of service.

MitigationUpgrade to Sentinel LDK RTE version 7.55 or later to address the stack overflow vulnerability in the custom XML-parser.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify if Sentinel products are installed
    Check the system for installed Gemalto Sentinel software such as Sentinel HASP, Sentinel LDK, or HASP SRM. Look for related services, installed programs, or driver files associated with these products.
    Affected if Any of these Sentinel products are found on the system
  2. Determine the installed Sentinel LDK RTE version
    Locate and inspect the version information for Sentinel LDK Runtime Environment (RTE) installation. This may be found in installed program details, version files, or product information dialogs.
    Affected if The installed version cannot be determined or is <= 7.50
  3. Compare version against affected range
    Compare the discovered Sentinel LDK RTE version against the affected range of versions <= 7.50
    Affected if The installed version is 7.50 or earlier
  4. Verify XML parser accessibility
    Determine whether the custom XML-parser functionality is accessible or exposed. This may involve checking if the Sentinel service accepts XML input over network connections or API calls.
    Affected if The XML parser is accessible and the version is <= 7.50

A system is affected if Sentinel LDK RTE version 7.50 or earlier is installed and the custom XML-parser is accessible for remote or local input.
