Security fixes that addresses issues in 1.2 will be back-ported from 1.4 by either A) upstream, or if that fails B) the Debian maintainer, or if that also fails, C) Debian security team. Thats the promise made by The Debian security team which cover the latest stable major release, and for the prior stable release for one year.

And it works. Most of all fixes are done by A or B, but the promise is one which the security team takes very serious. For one release, the security team backported security updates for 4 years. A achievement of taking responsibility in a "open source" project if I ever saw one.
