| AppleがiPhoneやiPadなど向けiOS 17.7.1とiPadOS 17.7.1をリリース! |
Appleは28日(現地時間)、iPhoneおよびiPod touch向けプラットフォーム「iOS」とiPad向けプラットフォーム「iPadOS」において前バージョン「iOS 17」や「iPadOS 17」の最新版「iOS 17.7.1(21H216)」および「iPadOS 17.7.1(21H216)」を提供開始したとお知らせしています。
対象機種はiOS 17やiPadOS 17の対応機種でiPhone XSシリーズやiPhone XR以降やiPhone SE(第2世代)以降、iPadOS 17はiPad(第6世代以降)およびiPad mini(第5世代以降)、iPad Air(第3世代以降)、12.9インチiPad Pro(第2世代以降)、10.5インチiPad Pro、11インチiPad Pro(第1世代以降)の各製品にて無料で更新可能となっており、次の最新バージョン「iOS 18」や「iPadOS 18」も提供開始されているため、iOS 18やiPadOS 18の対象機種はiOS 18やiPadOS 18またはiOS 17.7.1やiPadOS 17.7.1を選んで更新できます。
変更点は重要なセキュリティーアップデートが含まれているとしており、Kernelに関する「CVE-2024-44239」やShortcutsに関する「CVE-2024-44269」、Accessibilityに関する「CVE-2024-44274」、ImageIOに関する「CVE-2024-44215」および「CVE-2024-44297」などといったCVEに登録されている17個の脆弱性が修正されており、同社ではいくつかの脆弱性が悪用された可能性があるという報告を認識していると説明しています。
その他、すでに紹介しているようにiOSおよびiPadOSの最新バージョン「iOS 18.1」および「iPadOS 18.1」がリリースされているほか、スマートウォッチ「Apple Watch」向け「watchOS 11.1」、パソコン「Mac」向け「macOS Sequoia 15.1」、スマートテレビ「Apple TV」向け「tvOS 18.1」、スマートヘッドセット「Apple Vision Pro」向け「visionOS 2.1」なども配信開始しています。
Appleでは2021年に提供開始したiOS 15およびiPadOS 15から一定期間は次の最新バージョンに更新せずに既存のバージョンに留まる機能を提供しており、今年も最新のiOS 18やiPadOS 18の正式版が配信開始されましたが、引き続いてしばらくiOS 17やiPadOS 17で使う場合を対象にセキュリティー修正のみを行ったソフトウェア更新を提供しており、今回は前回のiOS 17.7およびiPadOS 17.7に続いてiOS 17.7.1およびiPadOS 17.7.1が提供開始されました。
iOS 17やiPadOS 17の対象機種の場合には「設定」→「情報」→「ソフトウェア・アップデート」を表示すると、画面の下部に「その他の利用可能なアップデート」として「iOS 18にアップグレード」または「iPadOS 18にアップグレード」が表示されるのでそこからiOS 18やiPadOS 18に更新できるほか、iOS 18やiPadOS 18にアップグレードを選ばない場合にはiOS 17.7.1やiPadOS 17.7.1の更新画面で「ダウンロードしてインストール」を押せばiOS 17.7.1やiPadOS 17.7.1に更新されます。
なお、これまでのAppleの動きからするとしばらくはiOS 17やiPadOS 17へのセキュリティー修正が継続して提供されると思われます。なお、単体でアップデートする場合のダウンロードサイズは手持ちのiPhone 13 Pro MaxでiOS 17.4.1からの場合では1.22GBとなっています。更新は従来通りにiTunesをインストールしたWindowsおよびMacとUSB-Lightningケーブルで接続しても実施できます。Appleが案内しているアップデートの内容およびセキュリティー修正は以下の通り。
