Commit message: Fixed bug #66060 (Heap buffer over-read in DateInterval)
CVE: CVE-2013-6712
CWE: CWE-119
Vulnerability description: The scan function in ext/date/lib/parse_iso_intervals.c in PHP through 5.5.6 does not properly restrict creation of DateInterval objects, which might allow remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted interval specification.
