NVD Description

Note: Versions mentioned in the description apply only to the upstream qt5-qtwebengine package and not the qt5-qtwebengine package as distributed by Alpine. See How to fix? for Alpine:3.20 relevant fixed versions and status.

There is a flaw in the xml entity encoding functionality of libxml2 in versions before 2.9.11. An attacker who is able to supply a crafted file to be processed by an application linked with the affected functionality of libxml2 could trigger an out-of-bounds read. The most likely impact of this flaw is to application availability, with some potential impact to confidentiality and integrity if an attacker is able to use memory information to further exploit the application.
