Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS : Qt Declarative vulnerability (USN-8357-1)

high Nessus Plugin ID 320480

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-8357-1 advisory.

 It was discovered that Qt Declarative did not properly validate the width and height attributes of image tags in the Text component of Qt Quick. An attacker could possibly use this issue to cause Qt Declarative to use excessive resources, leading to a denial of service.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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 packages.
