CVE-2015-9541

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 is a software toolkit for developing applications. The qt5-base packages contain base tools for string, xml, and network handling in Qt.

Security Fix(es):

• qt: XML entity expansion vulnerability (CVE-2015-9541)

• qt5-qtwebsockets: websocket implementation allows only limited size for frames and messages therefore attacker can cause DOS (CVE-2018-21035)

• qt: files placed by attacker can influence the working directory and lead to malicious code execution (CVE-2020-0569)

• qt: files placed by attacker can influence the working directory and lead to malicious code execution (CVE-2020-0570)

• qt5: incorrectly calls SSL_shutdown() in OpenSSL mid-handshake causing denial of service in TLS applications (CVE-2020-13962)

Updated qtbase5 packages fix security vulnerability:

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 (CVE-2015-9541).
