Apple has released updates for its iWork applications Keynote and Pages.
Keynote 2.0.2 (21.9MB) corrects a security problem. This problem meant a maliciously modified Keynote presentation could be "constructed to retrieve files from the local system", placing user data at risk.
Pages 1.0.2 (28.7MB) is described as "addressing issues with page navigation and organization".
Both updates are available through Software Update (assuming the applications are installed).
