Описание
This issue was addressed with improved memory handling. This issue is fixed in watchOS 11.5, tvOS 18.5, iOS 18.5 and iPadOS 18.5, macOS Sequoia 15.5, visionOS 2.5, Safari 18.5. Processing maliciously crafted web content may lead to an unexpected Safari crash.
A flaw was found in WebKitGTK. Processing malicious web content can cause a use-after-free issue due to improper memory handling and result in an unexpected crash.
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.
