CVE-2025-24201
Description
A flaw was found in WebKitGTK. Processing malicious web content can trigger an out-of-bounds write due to improper checks to prevent unauthorized actions, causing a break out of Web Content sandbox.
Statement
This vulnerability is only a risk for servers which utilize a GUI for system administration. This vulnerability can only be exploited when specific packages are used with a graphical interface to process untrusted web content, via GNOME for example.
Mitigation
Systems which do not rely on a GUI for system administration (commonly referred to as "headless") should confirm that GNOME shell and WebKitGTK are not present on the system.
WebKitGTK3 is no longer used and can therefore be uninstalled without consequence.
WebKitGTK4 is used in Red Hat Enterprise Linux 7 by the following packages: evolution-data-server, glade, gnome-boxes, gnome-initial-setup, gnome-online-accounts, gnome-shell, shotwell, sushi and yelp.
To mitigate this vulnerability, consider removing certain GNOME packages. Note that uninstalling these packages will break functionality in GNOME, however the server can still be used via the terminal interface.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Integrity
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
Write operations could cause memory corruption. In some cases, an adversary can modify control data such as return addresses in order to execute unexpected code.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
Attempting to access out-of-range, invalid, or unauthorized memory could cause the product to crash.
Other
Technical Impact: Unexpected State
Subsequent write operations can produce undefined or unexpected results.
