CVE-2013-6712: Apple Mac OS X

Medium severity, CVSS 5.0. EPSS: 4.6% chance of exploitation in the next 30 days.

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.
