Severity: Normal Title: QtGui: Arbitrary code execution Date: July 27, 2020 Bugs: #719732 ID: 202007-38

Synopsis ========
A use-after-free was discovered in QtGui's Markdown handling code possibly allowing a remote attacker to execute arbitrary code.
Background ==========
QtGui is a module for the Qt toolkit.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-qt/qtgui < 5.14.2 >= 5.14.2
Description ===========
QtGui's setMarkdown has a use-after-free related to QTextMarkdownImporter::insertBlock.
Impact ======
A remote attacker could possibly execute arbitrary code with the privileges of the process, or cause a Denial of Service condition.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All QtGui users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-qt/qtgui-5.14.2"
Note that the Qt suite is best kept in sync, so a world upgrade may be advisable to keep your system in a good state.
