CVE-2017-16663
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 · uneditedIn sam2p 0.49.4, there are integer overflows (with resultant heap-based buffer overflows) in input-bmp.ci in the function ReadImage, because "width * height" multiplications occur unsafely.
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 confidenceInteger overflow in sam2p's BMP image parser allows heap-based buffer overflow via maliciously crafted BMP files. The ReadImage function in input-bmp.ci calculates buffer size using unsafe 'width * height' multiplication without validating that the result fits in the allocated type, causing undersized buffer allocation followed by overflow during image data写入.

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.
-
Check if sam2p is installedRun 'which sam2p' or 'sam2p --version' to locate the binary and get version informationAffected if sam2p is installed and version equals 0.49.4 exactly
-
Verify sam2p versionRun 'sam2p --version' and compare the output to 0.49.4Affected if Version displayed is exactly 0.49.4 (note: this version is affected; other versions may have different status)
-
Identify the vulnerable BMP parser componentLocate the input-bmp.ci file in the sam2p installation directory or source codeAffected if The file input-bmp.ci exists and contains the ReadImage function with width*height buffer calculation
-
Confirm BMP processing capability is presentRun 'sam2p --help' or check available image format handlersAffected if BMP format is listed as a supported input format (the vulnerable code path requires BMP input)
-
Test BMP parsing with custom fileCreate or obtain a BMP file with very large dimensions to observe behavior (forensic analysis only)Affected if Processing succeeds without allocation failure warning - may indicate undersized buffer was allocated (this is informational only)
You are affected if sam2p version 0.49.4 is installed and you process BMP image files using this tool.

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 dataAdd overflow-safe arithmetic for width/height calculations (e.g., check for overflow before multiplication using safe integer operations or limit maximum dimensions) and validate buffer allocation success before use.
