Explanation / Answer

Install security patches on applications ona regular basis is the best way to prevent vulnerability which can cause buffer overflow.

Patched version will start with an automatic update that reaches all Internet-connected systems running the software.

However, it cannot be assumed that such an update will provide sufficient coverage. Organizations or individuals may use the software on systems with limited access to the Internet.

These cases require manual updates. This means that news of the update needs to be distributed to any admins who may be using the software, and the patch must be made easily available for download.

Patch creation and distribution should occur as close to the discovery of the vulnerability as possible. Thus, minimizing the amount of time users and systems are vulnerable.
