✅ 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: Users should upgrade to the latest version. If this is not possible and the affected version of the Python mailcap module has to be used then applications that use mailcap module should verify user input before passing it to the mailcap module, and the returned command before executing it.
