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 iw_read_bmp_file function in imagew-bmp.c in libimageworsener.a in ImageWorsener 1.3.0 allows remote attackers to consume an amount of available memory via a crafted 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 · moderate confidence

The iw_read_bmp_file function in imagew-bmp.c in libimageworsener.a in ImageWorsener 1.3.0 lacks proper bounds checking when parsing BMP files, allowing a crafted BMP file to trigger excessive memory allocation leading to memory exhaustion and denial of service.

MitigationUpgrade to a patched version of ImageWorsener when available. Until then, implement file size limits and memory allocation bounds checking before processing BMP files with the 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. Locate ImageWorsener installation
    Search for the libimageworsener library file on the system using commands like 'find / -name "libimageworsener*" 2>/dev/null' or check common library directories (/usr/lib, /usr/local/lib, /opt). Also check for the 'imageworsener' binary or any application that links against it using 'ldd' or 'dpkg -l' (Debian) or 'rpm -qa' (RHEL).
    Affected if ImageWorsener library or executable is found on the system
  2. Determine installed version
    Run 'imageworsener --version' if the binary exists, or query the package manager: 'dpkg -l | grep imageworsener' (Debian) or 'rpm -qa | grep imageworsener' (RHEL). If the library is standalone, check any version information in the filename or associated metadata files.
    Affected if The version reported is exactly 1.3.0
  3. Verify vulnerable component exists
    Confirm the presence of the file imagew-bmp.c compiled into libimageworsener.a by checking the library with 'ar -t libimageworsener.a | grep -i bmp' or inspecting the library symbols with 'nm libimageworsener.a | grep iw_read_bmp_file'.
    Affected if The iw_read_bmp_file function from imagew-bmp.c is present in the installed library
  4. Check if BMP processing is in use
    Identify whether any application or service links to libimageworsener and processes BMP files. Review application dependencies with 'ldd <application>' or check application logs/configs for BMP file handling. Look for processes that accept image input from untrusted sources.
    Affected if An application links against libimageworsener and processes BMP files from users or external sources
  5. Inspect resource limits
    Review system memory limits (ulimit -v, ulimit -m) and container/pod resource constraints (Kubernetes memory limits, Docker memory flags) to see if there are safeguards against memory exhaustion. Also check if any application-level size limits exist for uploaded images.
    Affected if No memory allocation bounds or file size limits are enforced when processing BMP files

The environment is affected if ImageWorsener version 1.3.0 is installed with the libimageworsener.a library containing the iw_read_bmp_file function and BMP files are processed without memory allocation limits.

Mitigation

Upgrade to a patched version of ImageWorsener when available. Until then, implement file size limits and memory allocation bounds checking before processing BMP files with the library.
