Package comaintainer statement: NOT VULNERABLE. This is a vulnerability in the QtImageFormats ICNS (Apple icon format) image loader plugin, in the file src/plugins/imageformats/icns/qicnshandler.cpp. That plugin was newly introduced in Qt 5.3 and was not included in any version of Qt 3 or 4. Nor was it backported in any Fedora package of those Qt versions. Hence, the qt3 (Qt 3) and qt (Qt 4) Fedora packages cannot possibly be vulnerable to this vulnerability.
