✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 Workaround: 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. Workaround: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability. Workaround: This vulnerability can be mitigated by setting the environment variable JSC_useWebAssembly=0, which will disable support for WebAssembly. It's not necessary to set this environment variable if you're already using JavaScriptCoreUseJIT=0 to mitigate other CVEs because WebAssembly depends on JIT. Workaround: This vulnerability can be mitigated by setting the environment variable JSC_useDFGJIT=0, which will disable the data flow graph JIT tier. It's not necessary to set this environment variable if you're already using JavaScriptCoreUseJIT=0 to mitigate other CVEs. Workaround: Do not process or load untrusted web content. Please update the affected package as soon as possible.
