CVE-2015-2754
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 · uneditedFreeXL before 1.0.0i allows remote attackers to cause a denial of service (stack corruption) and possibly execute arbitrary code via a crafted workbook, related to a "premature EOF."
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 confidenceFreeXL before version 1.0.0i contains a stack corruption vulnerability triggered when parsing a crafted Excel workbook file. The vulnerability stems from improper handling of premature end-of-file (EOF) conditions during workbook parsing, which can overwrite stack memory and potentially allow arbitrary code execution.

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 FreeXL library is presentSearch for the FreeXL shared library on the system (commonly named libfreexl.so or similar) using locate, find, or your package managerAffected if FreeXL library is found on the system
-
Determine installed FreeXL versionQuery the installed package version via your system package manager (dpkg for Debian, rpm for Red Hat-based systems) or inspect the library binary metadataAffected if The returned version is below 1.0.0i (for example, 1.0.0h or earlier)
-
Identify applications using FreeXLReview any installed GIS or data processing applications known to depend on FreeXL (such as Gaia GIS or spatial database tools like SpatiaLite)Affected if Applications that link against FreeXL are present and configured to process Excel files
-
Confirm Excel file processing workflowAudit any workflows, scripts, or services that parse .xls or .xlsx files using FreeXL-based toolsAffected if Untrusted or external Excel files are processed by FreeXL-enabled applications
You are affected if FreeXL version 1.0.0h or earlier is installed AND any application uses FreeXL to parse Excel files, as the stack corruption triggers during crafted workbook parsing.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade FreeXL to version 1.0.0i or later. If upgrading is not immediately feasible, restrict access to untrusted workbook files and validate all Excel files before processing.
