This signature detects attempts to exploit a known vulnerability in the PHP php_parserr. A successful attack can lead to a arbitrary code execution.
Heap-based buffer overflow in the php_parserr function in ext/standard/dns.c in PHP 5.6.0beta4 and earlier allows remote servers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted DNS TXT record, related to the dns_get_record function.
