smith (CVE-2023-32434)
This write-up presents an exploit for a vulnerability in the XNU kernel: Assigned CVE-2023-32434. Fixed in iOS 16.5.1 and macOS 13.4.1. Reachable from the WebContent sandbox and might have been actively exploited. *Note that this CVE fixed multiple integer overflows, so it is unclear whether or not the integer overflow used in my exploit was also used in-the-wild. Moreover, if it was, it might not have been exploited in the same way. The exploit has been successfully tested on: iOS 16.3, 16.3.1, 16.4 and 16.5 (iPhone 14 Pro Max) macOS 13.1 and 13.4 (MacBook Air M2 2022) All code snippets shown below are from xnu-8792.81.2.

An error as small as a single flipped memory bit is all it takes to expose a private key. The vulnerability occurs when there are errors during the signature generation that takes place when a client and server are establishing a connection. It affects only keys using the RSA cryptographic algorithm, which the researchers found in roughly a third of the SSH signatures they examined. That translates to roughly 1 billion signatures out of the 3.2 billion signatures examined. Of the roughly 1 billion RSA signatures, about one in a million exposed the private key of the host.
