Описание
A memory initialization issue was addressed with improved memory handling. This issue is fixed in Safari 26.2, iOS 26.2 and iPadOS 26.2, macOS Tahoe 26.2, tvOS 26.2, visionOS 26.2, watchOS 26.2. Processing maliciously crafted web content may disclose internal states of the app.
A flaw was found in WebKitGTK. Processing malicious web content can cause a memory initialization issue due to improper memory handling and result 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. Due to this reason, this flaw has been rated with a moderate severity.
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.
