The release is a continuation of a broad program by Adobe to improve the security of its products, which includes the introduction of a regular patching cycle timed with Microsoft's Patch Tuesday releases.
Adobe also uses a sandbox in its Reader X product, which was released in November. Reader's sandbox seals the application off from attacks designed to tamper with, for example, a computer's file system or registry. The sandbox interacts with the file system, but those communications go through a broker, which limits particular actions.
