medium Nessus Plugin ID 156880

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5241-1 advisory.

- An issue was discovered in Qt before 5.11.3. A malformed SVG image causes a segmentation fault in qsvghandler.cpp. (CVE-2018-19869)

- 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)

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

Solution

Update the affected libqt5svg5, libqt5svg5-dev and / or qtsvg5-examples packages.
