Until these re-writable firmware areas are locked down or the code is open-sourced and vastly simplified, it is likely to remain a rich environment for malicious adversaries. Unfortunately most end users must blindly trust the hardware producer, so it probably better to install non-free updates rather than risk being vulnerable to known attacks in the wild. On the one hand it may fix vulnerabilities, but on the other hand an update may introduce a new backdoor. Updating firmware may or may not improve security. If the process fails or the newer version performs worse, the process can be reverted. Old firmware should always be saved before upgrading. If firmware can be upgraded, this is usually possible via a program created by the provider.

While utility programs are often available to update BIOS, firmware in other devices is rarely updated and mechanisms for detecting and updating firmware is not standardized. Therefore, it is difficult to fix functionality or security issues after the hardware has shipped. The major problem with updating firmware is that it cannot be done automatically in most cases.
