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
Buffer overflow in the readgifimage function in gif2tiff.c in the gif2tiff tool in LibTIFF 4.0.6 allows remote attackers to cause a denial of service (segmentation fault) via a crafted gif file.

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

Buffer overflow vulnerability in the readgifimage function in gif2tiff.c within the gif2tiff tool of LibTIFF 4.0.6. The vulnerability is triggered when processing a crafted GIF file, leading to a buffer overflow that causes a segmentation fault and denial of service.

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. Check if gif2tiff tool is installed
    Run 'which gif2tiff' or 'gif2tiff -h' to see if the tool exists on the system
    Affected if gif2tiff is installed and accessible to users or automated processes
  2. Determine the installed LibTIFF version
    Run 'gif2tiff -v' or check the library version via 'tiffinfo -version' or by querying the installed libtiff package (e.g., 'dpkg -l libtiff*' or 'rpm -qi libtiff')
    Affected if The installed version is 4.0.6 or any earlier version (versions <= 4.0.6)
  3. Identify processes or workflows that use gif2tiff
    Search for scripts, cron jobs, or applications that invoke gif2tiff, and review any file processing pipelines that handle GIF to TIFF conversion
    Affected if gif2tiff is used in any automated or manual workflow to convert GIF files
  4. Check file access controls on gif2tiff
    Review file permissions on the gif2tiff binary and determine which users or groups can execute it (e.g., 'ls -la $(which gif2tiff)')
    Affected if Untrusted users have execute access to gif2tiff and could feed it crafted GIF files

A system is affected if it runs LibTIFF version 4.0.6 or earlier AND has the gif2tiff tool installed and accessible, where untrusted GIF files could be processed through it.
