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
The bm_readbody_bmp function in bitmap_io.c in potrace before 1.13 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a crafted BMP image, a different vulnerability than CVE-2016-8695 and CVE-2016-8696.

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

The bm_readbody_bmp function in bitmap_io.c in potrace versions before 1.13 contains a NULL pointer dereference vulnerability when parsing specially crafted BMP images, causing a denial of service (crash). The vulnerability is triggered during the body reading phase of BMP processing.

MitigationUpdate potrace to version 1.13 or later to obtain the patched bm_readbody_bmp function. Additionally, implement input validation to reject malformed BMP files before processing.

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. Confirm potrace is installed
    Run 'potrace --version' or check your package manager for the potrace package
    Affected if potrace is installed and the version reported is 1.12 or earlier
  2. Identify the exact potrace version
    Execute 'potrace --version' and note the version number displayed
    Affected if The version shown is 1.12 or any version lower than 1.13
  3. Verify the vulnerable code path exists
    Check if the file bitmap_io.c exists in your potrace source (if compiled from source), specifically the bm_readbody_bmp function
    Affected if The source file contains bm_readbody_bmp and the version is unpatched
  4. Determine if BMP processing is in use
    Review any scripts or applications that invoke potrace to process BMP input files
    Affected if potrace is being used to convert BMP files, either directly or through front-end tools

You are affected if potrace version 1.12 or earlier is installed and is used to process BMP image files

From vendor data
Upgrade available Upgrade to a release after 1.12
Interim mitigation

Update potrace to version 1.13 or later to obtain the patched bm_readbody_bmp function. Additionally, implement input validation to reject malformed BMP files before processing.
