CVE-2014-9679
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 · uneditedInteger underflow in the cupsRasterReadPixels function in filter/raster.c in CUPS before 2.0.2 allows remote attackers to have unspecified impact via a malformed compressed raster file, which triggers a 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 confidenceInteger underflow in the cupsRasterReadPixels function in CUPS filter/raster.c allows remote attackers to cause a buffer overflow via a malformed compressed raster file. This occurs when processing print jobs containing specially crafted raster images, leading to potential arbitrary code execution or 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 checksWork through these to decide whether this CVE applies to you.
-
Check installed CUPS versionRun 'cups-config --version' or query your system's package manager for the cups package versionAffected if Version is 2.0.1 or earlier (any version number less than 2.0.2)
-
Confirm CUPS is running and accepting print jobsCheck if the CUPS service is active and listening on port 631 (e.g., 'systemctl status cups' or 'netstat -an | grep 631')Affected if CUPS daemon is running and accepting print job submissions
-
Verify raster filter is presentCheck for the presence of raster processing filters in the CUPS filter directory (typically /usr/lib/cups/filter/ or /usr/libexec/cups/filter/)Affected if Raster filters are installed and available to process print jobs
-
Check if print queues accept external job submissionsReview CUPS configuration (/etc/cups/cupsd.conf) for any ACLs or restrictions limiting who can submit print jobsAffected if Print queues allow submissions from untrusted or external network sources
You are affected if CUPS version is 2.0.1 or earlier AND the CUPS service is running with raster print job processing enabled and accessible to untrusted sources.
Generated from the published advisory. Verify against your own configuration.
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.
From vendor dataUpgrade CUPS to version 2.0.2 or later, or apply the specific patch for the integer underflow in cupsRasterReadPixels. Additionally, restrict print job submissions to trusted sources and implement network segmentation for print servers.
