Adobe Flash Player (Windows/Mac) セキュリティアップデート [APSB14-09]

Adobe Systemsは4月8日(現地時間)、Flash Playerのセキュリティアップデートを提供開始しました。Windows/Mac/Linux。


優先度1: この優先度のアップデートは、対象として公表されている製品バージョンとプラットフォームにおいて、現在攻撃の対象となっている脆弱性、または攻撃対象になるリスクが比較的に高い脆弱性を解決します。この優先度のアップデートは、システム管理者によって直ちに適用されることを推奨します(例えば72時間以内)。

このアップデートによりFlash Playerは (Windwos/Mac)、 (Linux)が最新に。
Flash Playerインストール済みのGoogle ChromeやInternet Explorer 10/11では、自動的に最新版へアップデートされます。

あわせて、Adobe AIRのWindows/Mac版も にアップデートされています。

The new features for AIR and Flash Player are:

  • Enhanced Supplementary Character Support for TextField
    Characters from the Basic Multilingual Plane (BMP) with Unicode code points between U+10000 and U+10FFFF now work correctly in TextField controls. This change greatly enlarges the code point range we support, and now includes characters like emoticons and complex CCJK characters.
  • New Stage3D Texture Wrapping Modes
    Developers can currently set the wrapping mode of a texture to either clamp or repeat. Using the repeat option will repeat the texture on both the U and V axis. However, in some use cases, you may only want to repeat the texture on either the u or v axis.This is now possible with the introduction of two new parameters:
  • Stage3D Anti-Aliasing for Texture Rendering
    Anti-Aliasing is a useful for improving perceived image quality. Hardware based Multisampling Anti-Aliasing (MSAA) is now available on all desktop platforms. To enable MSAA, set the level from 0 to 4 using the antiAlias property of the Context3D.setRenderToTexture() method.0 = 1 subsample, no antialiasing
     1 = 2 subsamples, minimum quality antialiasing
     2 = 4 subsamples, medium quality antialiasing
     3 = 8 subsamples, high quality antialiasing
     4 = 16 subsamples, maximum quality antialiasing
  • GamePreview with Adobe AIR
    Adobe AIR’s new Game Preview feature (for Android platforms only) lets users try your game and experience it first hand without installing a separate application. This feature is not restricted to games built using AIR but is available to all developers, irrespective of the technology that you may use to build your application. The fact that the AIR runtime is installed on more than 50 million devices, greatly multiplies the chances of your game being previewed and subsequently installed by game enthusiasts. Please see Game Preview With Adobe AIR for more details.
  • Improved Packaging Engine – iOS – BETA
    The new packaging engine is now more stable and works fine with a large number of apps. We have now added support for Action Script debugging and Advanced Telemetry support. To enable this feature, please use “-useLegacyAOT no” in the ADT command, before the signing options. As of now, this feature is not available within Flash Pro but it can still be used with Flash builder by adding the parameter -useLegacyAOT under the “Customize launch” option.Here is an example ADT command for compiling an applications using “-useLegacyAOT no”:
     adt -package -target ( ipa-test | ipa-debug | ipa-app-store | ipa-ad-hoc) -useLegacyAOT no -provisioning-profile -keystore -storetype pkcs12 -storepass xxxx HelloWorld.ipa Helloworld-app.xml HelloWorld.swf
  • Relocated Full Screen Video Warning to Top of Screen
    We’ve made a small tweak to the “Press Esc to exit full screen mode” warning that is displayed for full screen video. We’ve received feedback from developers and users that the dialog obscures content. We wanted to make a change that both satisfies security concerns and customer viewing enjoyment. To reduce the impact of the dialog on the on-screen content, we’ve moved the dialog to the top of the screen.
