Red Hat has released updated qt6-qtbase packages (version 6.12.0-1.2.hum1) that address this vulnerability. Users should apply these updates to remediate the issue. Additionally, it is recommended to ensure client applications only connect to trusted HTTP endpoints and configure application network settings to restrict maximum allowed response headers and body buffer sizes where supported.
Description
A resource consumption vulnerability exists in the Qt Network module's HTTP response handling.
