Apple thanking the maker of an iPhone jailbreak tool? Well, now I've seen everything...
Apple has issued an update to address a potentially serious security flaw it re-opened in the latest version of iOS. Monday's iOS 12.4.1 update contains a single fix: a patch to address CVE-2019-8605. The use-after-free vulnerability would let an application gain the ability to execute arbitrary code with system privileges. …
"Jailbreaks aside, the re-exposure of the bug was embarrassing for Apple and potentially dangerous for end-users."
It is indeed very embarrassing. It shows IOS source code is managed in a non-professional way.
Never should have work on 12.4 be based with, apparently, part of 12.2 code like was seemingly the case.
I remember this issue (bugs in N-2, fixed in N-1, and still re-appearing in N) causing my company to dump the vendor entirely.
