CFNetwork HTTPProtocol Available for: OS X Lion v10.7.5, OS X Lion Server v10.7.5, OS X Mountain Lion v10.8.5, and OS X Mavericks 10.9.2 Impact: An attacker in a privileged network position can obtain web site credentials Description: Set-Cookie HTTP headers would be processed even if the connection closed before the header line was complete. An attacker could strip security settings from the cookie by forcing the connection to close before the security settings were sent, and then obtain the value of the unprotected cookie. This issue was addressed by ignoring incomplete HTTP header lines. CVE-ID CVE-2014-1296 : Antoine Delignat-Lavaud of Prosecco at Inria Paris

CoreServicesUIAgent Available for: OS X Mavericks 10.9.2 Impact: Visiting a maliciously crafted website or URL may result in an unexpected application termination or arbitrary code execution Description: A format string issue existed in the handling of URLs.

Intel Graphics Driver Available for: OS X Mountain Lion v10.8.5 and OS X Mavericks 10.9.2 Impact: A malicious application can take control of the system Description: A validation issue existed in the handling of a pointer from userspace. This issue was addressed through additional validation of pointers. CVE-ID CVE-2014-1318 : Ian Beer of Google Project Zero working with HP's Zero Day Initiative

IOKit Kernel Available for: OS X Mavericks 10.9.2 Impact: A local user can read kernel pointers, which can be used to bypass kernel address space layout randomization Description: A set of kernel pointers stored in an IOKit object could be retrieved from userland. This issue was addressed through removing the pointers from the object. CVE-ID CVE-2014-1320 : Ian Beer of Google Project Zero working with HP's Zero Day Initiative

Kernel Available for: OS X Mavericks 10.9.2 Impact: A local user can read a kernel pointer, which can be used to bypass kernel address space layout randomization Description: A kernel pointer stored in a XNU object could be retrieved from userland. This issue was addressed through removing the pointer from the object. CVE-ID CVE-2014-1322 : Ian Beer of Google Project Zero

Power Management Available for: OS X Mavericks 10.9.2 Impact: The screen might not lock Description: If a key was pressed or the trackpad touched just after the lid was closed, the system might have tried to wake up while going to sleep, which would have caused the screen to be unlocked. This issue was addressed by ignoring keypresses while going to sleep. This issue does not affect systems prior to OS X Mavericks. CVE-ID CVE-2014-1321 : Paul Kleeberg of Stratis Health Bloomington MN, Julian Sincu at the Baden-Wuerttemberg Cooperative State University (DHBW Stuttgart), Gerben Wierda of R&A, Daniel Luz

Ruby Available for: OS X Mavericks 10.9.2 Impact: Running a Ruby script that handles untrusted YAML tags may lead to an unexpected application termination or arbitrary code execution Description: An integer overflow issue existed in LibYAML's handling of YAML tags. This issue was addressed through additional validation of YAML tags. This issue does not affect systems prior to OS X Mavericks. CVE-ID CVE-2013-6393

Ruby Available for: OS X Lion v10.7.5, OS X Lion Server v10.7.5, OS X Mountain Lion v10.8.5, and OS X Mavericks 10.9.2 Impact: Running a Ruby script that uses untrusted input to create a Float object may lead to an unexpected application termination or arbitrary code execution Description: A heap-based buffer overflow issue existed in Ruby when converting a string to a floating point value. This issue was addressed through additional validation of floating point values. CVE-ID CVE-2013-4164

Security - Secure Transport Available for: OS X Mountain Lion v10.8.5 and OS X Mavericks 10.9.2 Impact: An attacker with a privileged network position may capture data or change the operations performed in sessions protected by SSL Description: In a 'triple handshake' attack, it was possible for an attacker to establish two connections which had the same encryption keys and handshake, insert the attacker's data in one connection, and renegotiate so that the connections may be forwarded to each other. To prevent attacks based on this scenario, Secure Transport was changed so that, by default, a renegotiation must present the same server certificate as was presented in the original connection. This issue does not affect Mac OS X 10.7 systems and earlier. CVE-ID CVE-2014-1295 : Antoine Delignat-Lavaud, Karthikeyan Bhargavan and Alfredo Pironti of Prosecco at Inria Paris
