An issue was discovered in certain Apple products. Safari before 10.0.1 is affected. iCloud before 6.0.1 is affected. iTunes before 12.5.2 is affected. tvOS before 10.0.1 is affected. The issue involves the "WebKit" component. It allows remote attackers to obtain sensitive information via a crafted web site.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An issue was discovered in certain Apple products. Safari before 10.0.1 is affected. iCloud before 6.0.1     is affected. iTunes before 12.5.2 is affected. tvOS before 10.0.1 is affected. The issue involves the     WebKit component. It allows remote attackers to obtain sensitive information via a crafted web site.
    (CVE-2016-4613)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3166-1 advisory.

    A large number of security issues were discovered in the WebKitGTK+ Web and JavaScript engines. If a user     were tricked into viewing a malicious website, a remote attacker could exploit a variety of issues related     to web browser security, including cross-site scripting attacks, denial of service attacks, and arbitrary     code execution.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Apple Safari installed on the remote Mac OS X or macOS host is prior to 10.0.1. It is, therefore, affected by multiple vulnerabilities in WebKit :

  - An unspecified flaw exists in state management due to     improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit this, via     specially crafted web content, to disclose sensitive     user information. (CVE-2016-4613)

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

The version of Apple iTunes running on the remote Windows host is prior to 12.5.2 It is, therefore, affected by multiple vulnerabilities :

  - An information disclosure vulnerability exists in WebKit     when handling the location attribute due to improper     validation of user-supplied input. An unauthenticated,     remote attacker can exploit this, via specially crafted     web content, to disclose sensitive information on the     user's system. (CVE-2016-4613)

  - Multiple memory corruption issues exist in WebKit due to     improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit these, via     specially crafted web content, to execute arbitrary     code. (CVE-2016-7578)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Apple iTunes installed on the remote Windows host is prior to 12.5.2. It is, therefore, affected by multiple vulnerabilities :

  - A cross-origin bypass vulnerability exists in WebKit due     to improper handling of the location attribute. An     unauthenticated, remote attacker can exploit this, by     convincing a user to visit a maliciously crafted     website, to bypass cross-origin policies and disclose     sensitive user data. (CVE-2016-4613)

  - Multiple memory corruption errors exist in WebKit due to     improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit these     issues, by convincing a user to visit a maliciously     crafted website, to execute arbitrary code.
    (CVE-2016-7578)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Versions of Apple TV earlier than 10.0.1 are vulnerable to the following issues :

 - A flaw exists in WebKit when handling the location attribute that allows a 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)
 - 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 NULL pointer dereference flaw exists in AppleSMC's smcHandleYPCEvent facility that is due to insufficient locking, which may allow a local attacker to gain elevated privileges. (CVE-2016-4678)
 - 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)
 - 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 race condition exists in multiple IOKit drivers related to how they use task struct pointers.  This may allow a local attacker to potentially execute arbitrary code with kernel-level privileges. (CVE-2016-7613)

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