Vulnerability Details:

CVE-ID: CVE-2014-3597

Description: PHP is vulnerable to a heap-based buffer overflow, caused by an incomplete fix related to improper bounds checking when parsing DNS TXT record. By sending an overly long string, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.

CVSS Base Score: 7.5
