An out-of-bounds read was addressed with improved input validation. This issue is fixed in Safari 18.6, watchOS 11.6, visionOS 2.6, iOS 18.6 and iPadOS 18.6, macOS Sequoia 15.6, tvOS 18.6. Processing maliciously crafted web content may disclose internal states of the app.
A flaw was found in WebKitGTK. Processing malicious web content can trigger an out-of-bounds read due to improper input validation, resulting in the disclosure of the internal states of the application.
Отчет
To exploit this flaw, an attacker needs to trick a user into processing or loading malicious web content.
Меры по смягчению последствий
Do not process or load untrusted web content with WebKitGTK. In Red Hat Enterprise Linux 7, the following packages require WebKitGTK4: evolution-data-server, glade, gnome-boxes, gnome-initial-setup, gnome-online-accounts, gnome-shell, shotwell, sushi and yelp. This vulnerability can only be exploited when these packages are installed in the system and being used via a graphical interface to process untrusted web content, via GNOME for example. In gnome-shell, the vulnerability can be exploited by an attacker from the local network without user interaction. To mitigate this vulnerability, consider removing these packages. Note that some of these packages are required by GNOME, removing them will also remove GNOME and other packages, breaking functionality. However, the server can still be used via the terminal interface. Additionally, WebKitGTK3 is not required by any package. Therefore, it can be removed without consequences or break of functionality.
