A memory corruption issue was addressed with improved memory handling. This issue is fixed in iOS 14.8 and iPadOS 14.8, Safari 15, tvOS 15, iOS 15 and iPadOS 15, watchOS 8. Processing maliciously crafted web content may lead to arbitrary code execution.

A cross-site request forgery flaw was found in etcd 3.3.1 and earlier. An attacker can set up a website that tries to send a POST request to the etcd server and modify a key. Adding a key is done with PUT so it is theoretically safe (can't PUT from an HTML form or such) but POST allows creating in-order keys that an attacker can send.
