CVE-2016-2317
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 · uneditedMultiple buffer overflows in GraphicsMagick 1.3.23 allow remote attackers to cause a denial of service (crash) via a crafted SVG file, related to the (1) TracePoint function in magick/render.c, (2) GetToken function in magick/utility.c, and (3) GetTransformTokens function in coders/svg.c.
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 confidenceMultiple buffer overflow vulnerabilities exist in GraphicsMagick 1.3.23 when parsing SVG files. The TracePoint, GetToken, and GetTransformTokens functions fail to properly validate bounds when processing crafted SVG input, allowing attackers to overflow buffers and cause denial of service via crash.

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.
-
Confirm GraphicsMagick is installedRun 'which gm' or 'gm -version' to locate the GraphicsMagick binaryAffected if GraphicsMagick is not found on the system - the CVE does not apply
-
Identify the installed GraphicsMagick versionRun 'gm -version' and check the version number in the outputAffected if The installed version is 1.3.23 exactly, matching the affected version range
-
Verify SVG format support is availableRun 'gm identify -list format' and look for SVG in the output, or attempt 'gm identify image.svg' on a test fileAffected if SVG support is listed as available or successfully processes SVG files - the vulnerable code path is reachable
-
Check if the SVG coder module is loadedRun 'gm identify -verbose test.svg' where test.svg is any SVG file, or check for svg.coder in the configurationAffected if SVG files can be read or identified by GraphicsMagick - the vulnerable parsing functions are active
You are affected if GraphicsMagick version 1.3.23 is installed AND SVG file processing is enabled and functional on your system.
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 GraphicsMagick to a patched version. If immediate upgrade is not feasible, disable SVG file processing or implement file type restrictions at the application layer to block untrusted SVG input.
