CVE-2014-1296: Apple iPhone OS

Medium severity, CVSS 4.3. EPSS: 1.9% chance of exploitation in the next 30 days.

CFNetwork in Apple iOS before 7.1.1, Apple OS X through 10.9.2, and Apple TV before 6.1.1 does not ensure that a Set-Cookie HTTP header is complete before interpreting the header's value, which allows remote attackers to bypass intended access restrictions by triggering the closing of a TCP connection during transmission of a header, as demonstrated by an HTTPOnly restriction.
