CVE-2015-7558
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 · uneditedlibrsvg before 2.40.12 allows context-dependent attackers to cause a denial of service (infinite loop, stack consumption, and application crash) via cyclic references in an SVG document.
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 confidencelibrsvg before version 2.40.12 contains a vulnerability in SVG document parsing where cyclic references within an SVG file can trigger an infinite loop or excessive stack consumption, leading to denial of service through application crash.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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.
-
Identify if librsvg is installedRun 'dpkg -l | grep librsvg' on Debian systems, or 'rpm -qa | grep librsvg' on RHEL-based systems, to list installed librsvg packagesAffected if The librsvg package appears in the package listing
-
Determine the installed librsvg versionRun 'dpkg -l librsvg2-3' or 'rpm -qi librsvg2' (exact package name may vary) to retrieve the version number of the installed libraryAffected if The reported version is 2.40.11 or earlier, or if no version is listed but the package is present on Debian 8.0
-
Check if SVG rendering is actively usedReview application logs or search for processes that handle SVG files, or check for SVG dependencies in application manifestsAffected if Applications or services process SVG documents using librsvg
-
Verify the library file path and modification dateLocate the librsvg shared library (typically librsvg-2.so.2 or similar in /usr/lib/) using 'find /usr -name "librsvg*" 2>/dev/null' and check its attributesAffected if The library file exists and was installed prior to the 2.40.12 patch release
A system is affected if librsvg is installed with a version of 2.40.11 or earlier and any application or service on that system processes SVG documents using the library.

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 dataUpdate librsvg to version 2.40.12 or later to patch the vulnerability. Identify all applications and components that depend on the vulnerable librsvg version and ensure they are rebuilt against the patched library.
