Description:
------------
Stefan Esser pointed out that the following commit fixes a heap-based buffer overflow in DNS TXT record parsing:


https://github.com/php/php-src/commit/b34d7849ed90ced9345f8ea1c59bc8d101c18468

A malicious server or man-in-the-middle attacker could possibly use this flaw to execute arbitrary code as the PHP interpreter if a PHP application uses dns_get_record() to perform a DNS query.
