PHP libraries and applications sometimes have vulnerabilities in which an attacker may inappropriately request construction of an object. The patch in this release does not deal with a specific vulnerability. Rather, it is defense in depth -- it removes an escalation vector by which hypothetical vulnerabilities (in CiviCRM or a related PHP library/application) could become more severe.
