Descriptions

Qt through 5.14 allows an exponential XML entity expansion attack via a crafted SVG document that is mishandled in QXmlStreamReader, a related issue to CVE-2003-1564.

Qt versiones hasta 5.14, permite un ataque de expansión de entidad XML exponencial por medio de un documento SVG diseñado que es manejado inapropiadamente en la función QXmlStreamReader, un problema relacionado con el CVE-2003-1564.

An XML Entity Expansion flaw was found in the QT library. Applications that use QT to load untrusted images, for example, SVG images, or untrusted XML documents, may be vulnerable to this flaw. This flaw allows an attacker to cause a denial of service.

Qt is a software toolkit for developing applications. The qt5-base packages contain base tools for string, xml, and network handling in Qt. Issues addressed include code execution and denial of service vulnerabilities.
