Library for rendering dynamic web content in Qt5 C++ and QML applications.
A use-after-free vulnerability has been found in the audio component of Qt WebEngine.
A remote attacker could entice a user to open a specially crafted media file in an application linked against Qt WebEngine, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.
There is no known workaround at this time.
All Qt WebEngine users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-qt/qtwebengine-5.14.1"
