PHP DNS TXT Record Handling CVE-2014-3597 Heap Buffer Overflow Vulnerability

PHP is prone to a remote heap-based buffer-overflow vulnerability because it fails to adequately bounds check user-supplied data before copying it into an insufficiently sized buffer.

Attackers can exploit this issue to execute arbitrary code in the context of the affected application. Failed exploit attempts will result in denial-of-service conditions.

Note: This issue is the result of an incomplete fix for the issue described in 68007 (PHP DNS TXT Record Handling Heap Buffer Overflow Vulnerability).
