It took just 15 seconds to hack the latest, finest, shiniest iPhone 13 Pro on stage at the Tianfu Cup in Oct, making use of a now-set iOS kernel bug.
As if the Log4Shell hellscape was not previously driving all people starkers, it is time to update iOS 15.2 and a crop of other Apple iGadgets, lest your iPhone get taken about by a destructive application that executes arbitrary code with kernel privileges.
To paraphrase one particular mobile security expert, the iOS 15.2 and iPadOS update – produced by Apple on Monday along with updates for macOS, tvOS and watchOS – is as bushy as a Lhasa Apso.

“If log4j was not more than enough, iOS 15.2 is out and it is wild,” tweeted Zuk Avraham, CEO at ZecOps, which marketplaces a software for cellular system log assessment. “Many distant and neighborhood vulnerabilities. If you care about your iPhone/iPad security you need to update before long.”

Apple’s security updates go over multiple vulnerabilities, including a distant jailbreak exploit chain and a selection of critical issues in the kernel and Safari web browser that ended up initially disclosed two months in the past at the Global Cyber Security Contest Tianfu Cup in China. Which is where by the shiniest new iPhone – the iPhone 13 Pro running the most new and absolutely patched edition of iOS 15..2 – was clobbered in record time, two times.
A single hack was executed stay, on phase, applying a distant code execution (RCE) exploit of the mobile Safari web browser. It was unleashed by a crew from Kunlun Lab and succeeded in a couple of eyeblinks: 15 seconds, to be exact.
Tracked as CVE-2021-30955, the issue that was picked aside by Kunlun Lab could have enabled a destructive software to execute arbitrary code with kernel privileges. Apple claimed it was a race situation that was addressed with “improved condition handling.”
“The kernel bug CVE-2021-30955 is the just one we tried [to] use to make our distant jailbreak chain but unsuccessful to finish on time,” Kunlun Lab’s main govt, @mj0011sec, said in a tweet. It also affects MacOS, in accordance to @mj0011sec, who’s also the previous CTO of Qihoo 360.
Where by Kunlun Lab unsuccessful, Group Pangu succeeded, controlling to remotely jailbreak the iPhone 13 Pro at the Tianfu Cup, marking the very first time that the iPhone 13 Pro was publicly jailbroken at a cybersecurity party. The accomplishment netted the group $330,000 in hard cash benefits.
Here’s the full listing of Apple’s security updates from Monday:
- macOS Monterey 12.1
- macOS Major Sur 11.6.2
- Security Update 2021-008 Catalina
- iOS 15.2 and iPadOS 15.2
- tvOS 15.2
- watchOS 8.3
Far more Fastened Bugs
Besides the distant jailbreak exploit flaw that toppled the iPhone 13 at the Tianfu Cup – CVE-2021-30955, the discovery of which was credited to Zweig of Kunlun Lab – Apple patched a whole of five flaws in Kernel and 4 in IOMobileFrameBuffer, a kernel extension for managing the monitor framebuffer, which is a portion of RAM that consists of a bitmap that drives a video clip display.
Below are the appropriate updates:
- CVE-2021-30927 and CVE-2021-30980: A use soon after cost-free issue that could make it possible for a destructive application to operate arbitrary code with kernel privileges.
- CVE-2021-30937: A memory corruption vulnerability that could enable a malicious application to operate arbitrary code with kernel privileges.
- CVE-2021-30949: A memory corruption issue that could enable a destructive software to run arbitrary code with kernel privileges.
- CVE-2021-30993: A buffer overflow issue that could permit an attacker in a privileged network placement to execute arbitrary code.
- CVE-2021-30983: A buffer overflow issue that could let an software to operate arbitrary code with kernel privileges.
- CVE-2021-30985: An out-of-bounds compose issue that could let a malicious application to operate arbitrary code with kernel privileges.
- CVE-2021-30991: An out-of-bounds examine issue that could allow for a destructive application to operate arbitrary code with kernel privileges.
- CVE-2021-30996: A race ailment that could let a destructive software to operate arbitrary code with kernel privileges.
Nothing Really Like Aged Cheese, Wine and Program
Miclain Keffeler, software security consultant at software security service provider nVisium, advised Threatpost on Tuesday that people “wild,” now-patched iOS 15.2 flaws “highlight why the security market recommends remaining on the N-1 or even the N-2 newest variation of software program patches.”
He pointed out that security practitioners “often glance at new variations of libraries and working programs as the hottest and biggest, but that normally will come at the cost of unfamiliar and new attack vectors.”
As this sort of, we want to allow time – and security testers – dictate the appropriate cadence to operate updates, he ongoing. “The distinct CVEs – which have now been patched – affected really core providers, meaning that shorter of having your iOS or Mac product off of the internet, the only avoidance is our weakest security security: human beings.
This string of vulnerabilities “only strengthens the security team’s solve that security is everyone’s career,” he ongoing. “Users will need to observe fantastic web hygiene as they go about their days by only downloading applications which are dependable, as nicely as browsing websites that they know are highly regarded and safe.”
