The version of Apple iOS running on the mobile device is prior to 10.2.1. It is, therefore, affected by multiple vulnerabilities in multiple components, the majority of which are remote code execution vulnerabilities. An unauthenticated, remote attacker can exploit these remote code execution vulnerabilities by convincing a user to visit a specially crafted website, resulting in the execution of arbitrary code in the context of the current user. The affected components are as follows :

  - Auto Unlock
  - Contacts
  - Kernel
  - libarchive
  - WebKit
  - WiFi

The remote host is affected by the vulnerability described in GLSA-201706-15 (WebKitGTK+: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in WebKitGTK+. Please       review the CVE identifiers referenced below for details.
  Impact :

    A remote attack can use multiple vectors to execute arbitrary code or       cause a denial of service condition.
  Workaround :

    There is no known workaround at this time.

According to its banner, the version of Apple TV on the remote device is prior to 10.1.1. It is, therefore, affected by multiple vulnerabilities :

  - A stack-based buffer overflow condition exists in     libarchive in the bsdtar_expand_char() function within     file util.c due to improper validation of certain     unspecified input. An unauthenticated, remote attacker     can exploit this, via a specially crafted archive, to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2016-8687)

  - A prototype access flaw exists in WebKit when handling     exceptions. An unauthenticated, remote attacker can     exploit this, via specially crafted web content, to     disclose cross-origin data. (CVE-2017-2350)

  - A type confusion error exists in WebKit when handling     SearchInputType objects due to improper validation of     certain unspecified input. An unauthenticated, remote     attacker can exploit this, via specially crafted web     content, to execute arbitrary code. (CVE-2017-2354)

  - An unspecified memory initialization flaw exists in     WebKit that allows an unauthenticated, remote attacker     to execute arbitrary code via specially crafted web     content. (CVE-2017-2355)

  - Multiple memory corruption issues exist in WebKit due to     improper validation of certain unspecified input. An     unauthenticated, remote attacker can exploit these, via     specially crafted web content, to execute arbitrary     code. (CVE-2017-2356, CVE-2017-2362, CVE-2017-2369,     CVE-2017-2373)

  - A use-after-free error exists in the host_self_trap mach     trap. A local attacker can exploit this, via a specially     crafted application, to dereference already freed memory     and thereby execute arbitrary code with kernel     privileges. (CVE-2017-2360)

  - A flaw exists in WebKit when handling page loading due     to improper validation of certain unspecified input.
    An unauthenticated, remote attacker can exploit this,     via specially crafted web content, to disclose     cross-origin data. (CVE-2017-2363)

  - A flaw exists in WebKit when handling variables due     to improper validation of certain unspecified input.
    An unauthenticated, remote attacker can exploit this,     via specially crafted web content, to disclose     cross-origin data. (CVE-2017-2365)

  - A heap buffer overflow condition exists in the     mach_voucher_extract_attr_recipe_trap() function due to     improper validation of certain unspecified input. A     local attacker can exploit this, via a specially     crafted application, to cause a denial of service     condition or the execution of arbitrary code with     kernel privileges. (CVE-2017-2370)

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

The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3200-1 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.

This update was imported from the SUSE:SLE-12-SP2:Update update project.

The version of Apple Safari installed on the remote macOS or Mac OS X host is prior to 10.0.3. It is, therefore, affected by multiple vulnerabilities :

  - A prototype access flaw exists in WebKit when handling     exceptions. An unauthenticated, remote attacker can     exploit this, via specially crafted web content, to     disclose cross-origin data. (CVE-2017-2350)

  - Multiple memory corruption issues exist in WebKit due to     improper validation of certain unspecified input. An     unauthenticated, remote attacker can exploit these, via     specially crafted web content, to corrupt memory,     resulting in the execution of arbitrary code.
    (CVE-2017-2354, CVE-2017-2356, CVE-2017-2362,     CVE-2017-2366, CVE-2017-2369, CVE-2017-2373)

  - An unspecified memory initialization flaw exists in     WebKit that allows an unauthenticated, remote attacker     to execute arbitrary code. (CVE-2017-2355)

  - An unspecified state management flaw exists that allows     an unauthenticated, remote attacker to spoof the address     bar. (CVE-2017-2359)

  - Multiple flaws exist in WebKit when handling page     loading due to improper validation of certain     unspecified input. An unauthenticated, remote attacker     can exploit these, via specially crafted web content, to     disclose cross-origin data. (CVE-2017-2363,     CVE-2017-2364)

  - A flaw exists in WebKit when handling variables due to     improper validation of certain unspecified input. An     unauthenticated, remote attacker can exploit this, via     specially crafted web content, to disclose cross-origin     data. (CVE-2017-2365)

This update addresses the following vulnerabilities :

  -     [CVE-2017-2350](https://cve.mitre.org/cgi-bin/cvename.cg     i?name=CVE-2017-2350),     [CVE-2017-2354](https://cve.mitre.org/cgi-bin/cvename.cg     i?name=CVE-2017-2354),     [CVE-2017-2355](https://cve.mitre.org/cgi-bin/cvename.cg     i?name=CVE-2017-2355),     [CVE-2017-2356](https://cve.mitre.org/cgi-bin/cvename.cg     i?name=CVE-2017-2356),     [CVE-2017-2362](https://cve.mitre.org/cgi-bin/cvename.cg     i?name=CVE-2017-2362),     [CVE-2017-2363](https://cve.mitre.org/cgi-bin/cvename.cg     i?name=CVE-2017-2363),     [CVE-2017-2364](https://cve.mitre.org/cgi-bin/cvename.cg     i?name=CVE-2017-2364),     [CVE-2017-2365](https://cve.mitre.org/cgi-bin/cvename.cg     i?name=CVE-2017-2365),     [CVE-2017-2366](https://cve.mitre.org/cgi-bin/cvename.cg     i?name=CVE-2017-2366),     [CVE-2017-2369](https://cve.mitre.org/cgi-bin/cvename.cg     i?name=CVE-2017-2369),     [CVE-2017-2371](https://cve.mitre.org/cgi-bin/cvename.cg     i?name=CVE-2017-2371),     [CVE-2017-2373](https://cve.mitre.org/cgi-bin/cvename.cg     i?name=CVE-2017-2373)

Additional fixes :

  - Make accelerating compositing mode on-demand again. By     default it will only be used for websites that require     it, saving a lot of memory on websites that don&rsquo;t     need it.

  - Release unused UpdateAtlas and reduce the tile coverage     on memory pressure.

  - The media backend now stores preloaded media in /var/tmp     instead of user cache dir.

  - Make inspector work again when accelerated compositing     support is disabled.

  - Fix a deadlock when the media player is destroyed.

  - Fix network process crashes when loading custom URI     schemes.

  - Fix overlay scrollbars that are over a subframe.

  - Fix a crash in GraphicsContext3D::drawArrays when using     OpenGL 3.2 core profile.

  - Fix BadDamage X errors happening when resizing the     WebView.

  - Fix several crashes and rendering issues.
