Tim: Stable Release Updates are described at https://wiki.ubuntu.com/StableReleaseUpdates. In general, a fix in more recent release is applied to an older one, the package is tested and the fix is (hopefully) rolled out.
In this specific case though, comment #24 and #25 mentions this will introduce new dependencies, and I don't know how that is dealt with.
