There have been multiple issues being attacked: 4.3.10 fixes a problem
where you could exploit code which accepted serialized data structures
directly from clients; most of the prolems were caused, however, by a
bug in phpBB which had nothing to do with this.

In either case the problem has very little to do with PHP - it's yet
another case of programmers not sanitizing input from untrusted
sources.
