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
Integer overflow in filter/texttopdf.c in texttopdf in cups-filters before 1.0.71 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted line size in a print job, which triggers a heap-based buffer overflow.

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

Integer overflow in the texttopdf filter (filter/texttopdf.c) in cups-filters before version 1.0.71 allows remote attackers to trigger a heap-based buffer overflow via a crafted line size in a print job, potentially leading to denial of service or arbitrary code execution.

MitigationUpgrade cups-filters to version 1.0.71 or later to patch the integer overflow vulnerability in the texttopdf filter.

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 cups-filters package version
    Run 'dpkg -l cups-filters' on Debian/Ubuntu, or 'rpm -q cups-filters' on RPM-based systems, to see the installed version number
    Affected if Version is lower than 1.0.71 (e.g., 1.0.70, 1.0.69, etc.)
  2. Check for texttopdf filter file
    Locate the texttopdf filter by running 'find /usr -name texttopdf 2>/dev/null' or check the CUPS filter directory (typically /usr/lib/cups/filter/ or /usr/lib64/cups/filter/)
    Affected if The texttopdf binary exists in the CUPS filter directory and the cups-filters version is below 1.0.71
  3. Verify CUPS print service status
    Run 'systemctl status cups' or 'service cups status' to check if the CUPS print service is active
    Affected if CUPS is running and uses an affected version of cups-filters with the texttopdf filter present

If cups-filters version is 1.0.70 or earlier, the system is vulnerable to the integer overflow when processing print jobs using the texttopdf filter.
