Sıkça Sorulan Sorular

What is CVE-2025-71436?

It is an arbitrary code execution vulnerability in raptor2, the Redland RDF parser toolkit (RDF/XML and N-Triples formats), fixed in the AlmaLinux 8 update ALSA-2026:94519.

Who is affected?

Systems with raptor2 installed where RDF data gets parsed — semantic-web applications, metadata processors and anything linking the Redland libraries.

How do I apply the fix?

Run dnf update raptor2 and restart applications that link the library so they reload the patched code.

Is raptor2 common on hosting servers?

Not commonly — it usually arrives as a dependency of semantic-web or metadata tooling. If installed, update it; if the erratum query shows nothing, it was pulled in by another package you can likely remove.
