Apple 又針對 iOS 12 釋出安全性更新了：「About the security content of iOS 12.5.7」。
Available for: iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini 2, iPad mini 3, and iPod touch (6th generation)
Impact: Processing maliciously crafted web content may lead to arbitrary code execution. Apple is aware of a report that this issue may have been actively exploited against versions of iOS released before iOS 15.1.
Description: A type confusion issue was addressed with improved state handling.
這次的更新是 backport 去年十二月在 Safari 16.2 上修正的 CVE-2022-42856：
A type confusion issue was addressed with improved state handling. This issue is fixed in Safari 16.2, tvOS 16.2, macOS Ventura 13.1, iOS 15.7.2 and iPadOS 15.7.2, iOS 16.1.2. Processing maliciously crafted web content may lead to arbitrary code execution.
所以這包跟上次一樣 (參考先前寫的 「iOS 12.5.6」這篇)，也是在修正 RCE 類的漏洞，這樣對於 iPhone 5S 等於是進入第九年的支援了。
之前在網路上有看到有人在猜是因為海外有很多異議人士拿這隻手機，所以美國政府「希望」Apple 能夠針對一些高危險性的安全漏洞提供更新？
