Gentoo Linux Security Advisory

Title: Qt WebEngine: Arbitrary code execution (GLSA 202004-04)
Severity: normal
Exploitable: local, remote
Date: 2020-04-01
Bug(s): #699328
ID: 202004-04


A heap use-after-free flaw in Qt WebEngine at worst might allow an
attacker to execute arbitrary code.


Library for rendering dynamic web content in Qt5 C++ and QML

Affected Packages

Package: dev-qt/qtwebengine
Vulnerable: < 5.14.1
Unaffected: >= 5.14.1
Architectures: All supported architectures


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"
