CVE-2013-3480
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 · uneditedInteger overflow in Sagelight 4.4 and earlier allows remote attackers to execute arbitrary code via crafted width and height dimensions in a BMP file, which triggers a heap-based buffer overflow.
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 confidenceSagelight 4.4 and earlier contains an integer overflow vulnerability in its BMP file parser. When parsing BMP files, the application calculates buffer sizes using width and height values from the file header without proper validation. Crafted dimensions can cause an integer overflow, resulting in an undersized buffer allocation, which leads to a heap-based buffer overflow when image data is written, enabling 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.
-
Locate Sagelight installation directorySearch for Sagelight in common installation locations such as C:\Program Files\Sagelight or C:\Program Files (x86)\Sagelight, or check Start Menu shortcuts and uninstall registry entries under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\UninstallAffected if Sagelight is installed on the system
-
Determine installed Sagelight versionRight-click the Sagelight executable (Sagelighteditor.exe), select Properties, and view the Version tab, or use PowerShell command: Get-Item 'C:\Program Files\Sagelight\Sagelighteditor.exe' | Select-Object VersionInfoAffected if Version information is available for comparison
-
Compare version against vulnerable rangeIf version is displayed as a string like 4.4, 4.3, 4.2, etc., compare numerically to 4.4 - any version <= 4.4 is affectedAffected if Installed version is 4.4 or lower (for example 4.4, 4.3, 4.2, 4.1, 4.0, or earlier)
-
Verify BMP file handling capabilityConfirm the Sagelight installation includes BMP file format support - this is typically built into the standard Sagelighteditor package as a basic image format capabilityAffected if BMP parsing functionality exists (standard in Sagelighteditor)
A user is affected if Sagelighteditor Sagelight version 4.4 or earlier is installed and the application can open BMP files, since the integer overflow in the BMP parser will trigger during file processing.

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 dataUpdate Sagelight to a version newer than 4.4. Avoid opening untrusted BMP files from unknown sources until the update is applied, as the vulnerability can be triggered via malicious file handling.
