TITLE

plural Apple Product IOKit In ASLR Vulnerabilities that circumvent protection mechanisms

DESCRIPTION

IOKit in Apple iOS before 7.1.1, Apple OS X through 10.9.2, and Apple TV before 6.1.1 places kernel pointers into an object data structure, which makes it easier for local users to bypass the ASLR protection mechanism by reading unspecified attributes of the object. This vulnerability allows remote attackers to disclose sensitive information on vulnerable installations of Apple OS X. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within IOKit. The issue lies in the storage of kernel pointers in an object's data structure that could be retrieved from userland. An attacker can leverage this vulnerability to leak kernel pointers. Multiple Apple products are prone to a local security-bypass vulnerability. Attackers can exploit this issue to bypass certain security restrictions and perform unauthorized actions. in the United States. Apple iOS is an operating system developed for mobile devices; Apple TV is a high-definition TV set-top box product; Apple OS X is a dedicated operating system developed for Mac computers. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 APPLE-SA-2014-04-22-1 Security Update 2014-002 Security Update 2014-002 is now available and addresses the following: CFNetwork HTTPProtocol Available for: OS X Lion v10.7.5, OS X Lion Server v10.7.5, OS X Mountain Lion v10.8.5, OS X Mavericks v10.9.2 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 v10.9.2 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. This issue was addressed through additional validation of URLs. CVE-ID CVE-2014-1315 : Lukasz Pilorz of runic.pl, Erik Kooistra FontParser Available for: OS X Mountain Lion v10.8.5 Impact: Opening a maliciously crafted PDF file may result in an unexpected application termination or arbitrary code execution Description: A buffer underflow existed in the handling of fonts in PDF files. This issue was addressed through additional bounds checking. This issue does not affect OS X Mavericks systems. CVE-ID CVE-2013-5170 : Will Dormann of CERT/CC Heimdal Kerberos Available for: OS X Mavericks v10.9.2 Impact: A remote attacker may be able to cause a denial of service Description: A reachable abort existed in the handling of ASN.1 data. This issue was addressed through additional validation of ASN.1 data. CVE-ID CVE-2014-1316 : Joonas Kuorilehto of Codenomicon ImageIO Available for: OS X Mountain Lion v10.8.5, OS X Mavericks v10.9.2 Impact: Viewing a maliciously crafted JPEG image may lead to an unexpected application termination or arbitrary code execution Description: A buffer overflow issue existed in ImageIO's handling of JPEG images. This issue was addressed through improved bounds checking. CVE-ID CVE-2014-1319 : Cristian Draghici of Modulo Consulting, Karl Smith of NCC Group Intel Graphics Driver Available for: OS X Mountain Lion v10.8.5, OS X Mavericks v10.9.2 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 v10.9.2 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 v10.9.2 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 v10.9.2 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. 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 v10.9.2 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. 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, OS X Mavericks v10.9.2 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, OS X Mavericks v10.9.2 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. CVE-ID CVE-2014-1295 : Antoine Delignat-Lavaud, Karthikeyan Bhargavan and Alfredo Pironti of Prosecco at Inria Paris WindowServer Available for: OS X Mountain Lion v10.8.5, OS X Mavericks v10.9.2 Impact: Maliciously crafted applications can execute arbitrary code outside the sandbox Description: WindowServer sessions could be created by sandboxed applications. This issue was addressed by disallowing sandboxed applications from creating WindowServer sessions.
