An update hook can do pretty much anything, and if it exits with 0 status code, the actual update succeeds. If it exists with any non-zero exit code, the update will fail. This is (usually) the basis for a lot of checks that people may want, from commit message format to access control at the ref (branch/tag) level for write operations.
