CVE-2023-45872Network attack vector

Application crash via invalid QML image source

Published Oct 9, 2024 · Updated Nov 12, 2024

Denial of service in Qt before 6.2.11 and 6.3.x through 6.6.0 allows remote attackers to crash applications via QML images. The QML image-loading path assumes an image with unidentified content is SVG and passes non-SVG data to Qt SVG, which crashes. Exploitation requires a Qt application to load an attacker-controlled image and affects only that application process; Qt 5.15.x and Qt 6.5.3 are unaffected.
