✅ 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: Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical example. Please update the affected package as soon as possible. Workaround: To mitigate this issue, avoid processing untrusted web content. Additionally, disabling the JavaScript JIT compiler can reduce the attack surface. For applications using WebKitGTK, set the environment variable `JavaScriptCoreUseJIT=0` before launching the application. This may impact performance for JavaScript-heavy web content.
