This is all Apple has to say about the update on the support page:
About OS X Mountain Lion 10.8.2 Supplemental Update 2.0
This update addresses an issue with Keychain that can affect 2012 Mac systems.
This update is recommended for all Mac systems introduced in 2012.
Fixing Keychain is important, so I’d go and take care of it now.
