Apple TV < 10.0.1 Multiple Vulnerabilities

High Nessus Plugin ID 94337

Synopsis

The remote Apple TV device is affected by multiple vulnerabilities.

Description

According to its banner, the version of Apple TV on the remote device is prior to 10.0.1. It is, therefore, affected by multiple vulnerabilities :

- A flaw exists in WebKit when handling the location attribute that allows an unauthenticated, remote attacker to bypass the cross-origin policies and disclose sensitive user information. (CVE-2016-4613)

- An out-of-bounds read error exists in the FontParser component when handling specially crafted font files that allows an unauthenticated, remote attacker to disclose sensitive information. (CVE-2016-4660)

- An unspecified flaw exists in the Sandbox Profiles component that allows a local attacker, via a specially crafted application, to disclose the metadata of photo directories. (CVE-2016-4664)

- An unspecified flaw exists in the Sandbox Profiles component that allows a local attacker, via a specially crafted application, to disclose the metadata of audio recordings. (CVE-2016-4665)

- Multiple memory corruption issues exist in Webkit due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit these to execute arbitrary code. (CVE-2016-4666, CVE-2016-4677, CVE-2016-7578)

- Multiple unspecified flaws exist in the System Boot component, within MIG generated code, due to improper validation of input. A local attacker can exploit these to terminate the system or execute arbitrary code with elevated privileges. (CVE-2016-4669)

- A memory corruption issue exists in the CoreGraphics component when handling specially crafted JPEG files. An unauthenticated, remote attacker can exploit this, via a specially crafted file, to cause a denial of service condition or the execution of arbitrary code.
(CVE-2016-4673)

- An unspecified logic issue exists in libxpc that allows a local attacker to execute arbitrary code with root privileges. (CVE-2016-4675)

- A flaw exists in libarchive due to improper path validation when creating temporary files during archive extraction. An unauthenticated, remote attacker can exploit this, via a symlink attack, to overwrite arbitrary files. (CVE-2016-4679)

- An unspecified flaw exists in the Kernel component due to improper sanitization of input. A local attacker can exploit this to disclose kernel memory contents.
(CVE-2016-4680)

- An overflow condition exists in the FontParser component due to improper validation when parsing font files. An unauthenticated, remote attacker can exploit this to cause a buffer overflow, resulting in a denial of service condition or the execution of arbitrary code.
(CVE-2016-4688)

- A flaw exists in the CFNetwork Proxies component when handling proxy credentials that allows a man-in-the-middle attacker to disclose sensitive user information. (CVE-2016-7579)

- A flaw exists in the AppleMobileFileIntegrity component due to improper validation of code signatures. A local attacker can exploit this to have a signed executable substitute code with the same team ID. (CVE-2016-7584)

- Multiple race conditions exist in various IOKit drivers related to how they use task struct pointers. A local attacker can exploit this to execute arbitrary code with kernel-level privileges. (CVE-2016-7613)

Note that only 4th generation models are affected by these vulnerabilities.

Solution

Upgrade to Apple TV version 10.0.1 or later. Note that this update is only available for 4th generation models.
