CVE-2014-1296: Apple iOS, macOS and tvOS may let attackers bypass cookie limits

CVE-2014-1296 · published 12 years ago

Summary

When a web connection is abruptly closed while a Set‑Cookie header is being sent, the affected Apple networking library can misinterpret the incomplete header. This can let a remote user evade the intended restrictions on a website’s cookies, potentially gaining access they should not have. Update the operating system to the latest version or apply any available patches to fix the issue.

Original advisory text

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.
