Debian DLA-2895-1 : qt4-x11 - LTS security update

high Nessus Plugin ID 157047

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2895 advisory.

 - Qt SVG in Qt 5.0.0 through 5.15.2 and 6.0.0 through 6.2.1 has an out-of-bounds write in QtPrivate::QCommonArrayOps<QPainterPath::Element>::growAppend (called from QPainterPath::addPath and QPathClipper::intersect). (CVE-2021-45930)

 - A flaw was found in Qt. An out-of-bounds read vulnerability was found in QRadialFetchSimd in qt/qtbase/src/gui/painting/qdrawhelper_p.h in Qt/Qtbase. While rendering and displaying a crafted Scalable Vector Graphics (SVG) file this flaw may lead to an unauthorized memory access. The highest threat from this vulnerability is to data confidentiality and the application availability. (CVE-2021-3481)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the qt4-x11 packages.

For Debian 9 stretch, these problems have been fixed in version 4
