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
Heap-based buffer overflow in the BMP reader (bmp.c) in Imager perl module (libimager-perl) 0.45 through 0.56 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via crafted 8-bit/pixel compressed BMP files.

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 confidence

Heap-based buffer overflow in Imager perl module's BMP reader (bmp.c) allows remote attackers to cause denial of service or potentially execute arbitrary code via crafted 8-bit/pixel compressed BMP files. The vulnerability affects versions 0.45 through 0.56.

MitigationUpgrade Imager perl module to version 0.57 or later to patch the buffer overflow. Alternatively, implement input validation to reject malformed BMP files before passing to the Imager library.

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 installed Imager perl module version
    Run `perl -MImager -e 'print Imager->VERSION'` or check your perl distribution's package manager for the Imager package version
    Affected if The version listed is 0.44, 0.44_1, 0.45, 0.45_2, 0.46, 0.47, 0.48, 0.49, 0.50, 0.51, 0.52, or 0.53 (falls within 0.44 through 0.56)
  2. Confirm BMP file processing is in use
    Search your codebase or application for calls to Imager's file reading functions (Imager::File::BMP, Imager::read, or image loading methods) that accept BMP input
    Affected if Your application loads or processes BMP format files using the Imager library
  3. Verify the vulnerable BMP reader component is loaded
    Check if Imager's BMP support module (typically bmp.c or the compiled BMP handler) is present in your perl library path, or trace runtime loading of Imager::File::BMP
    Affected if The BMP file handler module is loaded at runtime when processing image files
  4. Identify if 8-bit/pixel compressed BMP files are processed
    Review your application's image upload or processing logic to determine if it handles BMP files with 8-bit pixel depth and RLE compression
    Affected if Your application processes compressed 8-bit BMP files, which triggers the vulnerable code path in bmp.c

You are affected if the Imager perl module version is between 0.44 and 0.56 (inclusive) AND your application uses Imager to process BMP files, especially compressed 8-bit/pixel BMP files.

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.

Mitigation

Upgrade Imager perl module to version 0.57 or later to patch the buffer overflow. Alternatively, implement input validation to reject malformed BMP files before passing to the Imager library.
