An exploit would allow an attacker to remotely execute code and ultimate take over the system.\n\n[](<https://threatpost.com/newsletter-sign/>)\n\nApple on Monday urged affected device users to update as soon as possible: \u201cKeeping your software up-to-date is one of the most important things you can do to maintain your Apple product\u2019s security,\u201d said the company on Monday.\n\n## **What is Apple WebKit?**\n\nThe WebKit browser engine was developed by Apple for use in its Safari web browser \u2013 however, it is also used by Apple Mail, the App Store, and various apps on the macOS and iOS operating systems. The vulnerability stems from a memory-corruption issue in WebKit; [this type of bug occurs](<https://threatpost.com/memory-corruption-mitigations-doing-their-job/124728/>) when the contents of a memory location are modified in a way that exceeds the intention of the original program/language constructs \u2013 allowing attackers to execute arbitrary code.\n\nIn the case of this specific flaw, if WebKit processes specially-crafted, malicious web content, it could lead to successful exploitation, according to Apple.\n\nIn a real-world attack, \u201ca remote attacker can create a specially crafted web page, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system,\u201d [according to an advisory.](<https://www.cybersecurity-help.cz/vdb/SB2021030901>)\n\n## **What Apple Devices Are Affected?**\n\nApple pushed the updates out across a variety of devices.

Two of these \u2013 CVE-2021-1870 and CVE-2021-1871 \u2013 were discovered in WebKit (while the third, tracked as CVE-2021-1782, was found in the OS kernel).\n\nThe WebKit vulnerabilities are both logic issues that the update addresses with improved restrictions, according to Apple. Exploiting these flaws would allow a remote attacker \u201cto cause arbitrary code execution,\u201d the company said.\n\nThe security updates also come weeks after [Apple released its 2021 Platform Security guide](<https://threatpost.com/apple-2021-platform-security-guide/164094/>), outlining its current and year-ahead agenda for its device hardware, software and silicon security.

One bug, tracked as CVE-2021-1782, was found in the OS kernel, while the other two\u2013CVE-2021-1870 and CVE-2021-1871\u2013were discovered in the WebKit browser engine.\n\nThe most recent vulnerabilities apparently weren\u2019t known when Apple released iOS 14.2 and iPadOS 14.2, a comprehensive update that patched a total of 24 vulnerabilities [back in November](<https://threatpost.com/apple-patches-bugs-zero-days/161010/>). That update included fixes for three zero-day flaws discovered by the Google Project Zero team that were actively being exploited in the wild. \n[](<https://threatpost.com/newsletter-sign/>)Attackers also may be actively taking advantage of the latest bugs, according to Apple.

Security experts believe the three are part of an exploit chain attackers can use to escalate privileges and compromise a device after its unsuspecting user falls victim to a malicious website leveraging the WebKit flaw.\n\nAs is custom, however, Apple did not go into detail about how the bugs are being used in attacks, as it doesn\u2019t typically reveal this type of info until most of the affected devices are patched.\n\nThe proliferation of iPhones across the world makes news of any Apple iOS zero-day a security threat to its hundreds of millions of users, and thus a very big deal. In fact, four nation-state-backed advanced persistent threats (APTs) used a zero-day iPhone exploit in a highly publicized [espionage hack](<https://threatpost.com/zero-click-apple-zero-day-pegasus-spy-attack/162515/>) against Al Jazeera journalists, producers, anchors and executives late last year.\n\nPredictably, numerous [iPhone users](<https://twitter.com/Gurgling_MrD/status/1354191338221285377>), [tech professionals](<https://twitter.com/GustavoCols/status/1354160831366361089>) and [security experts](<https://twitter.com/Riazjavedbutt/status/1354307444961406976>) took to Twitter as news of the latest spate of iOS zero-days broke to warn iPhone users to update their devices immediately.\n\n\u201ciOS release notes are always comforting when you have firsts like this,\u201d [tweeted](<https://twitter.com/_DanielSinclair/status/1354299572177268737>) one iPhone user [Daniel Sinclair](<https://twitter.com/_DanielSinclair/status/1348631971480666112>) sarcastically. \u201c3 zero-days actively exploited in the wild. 2 involving WebKit.\u201d\n\nSinclair also [tweeted](<https://twitter.com/_DanielSinclair/status/1348631971480666112>) earlier in the month that his iPhone \u201cinexplicably became bricked,\u201d though it\u2019s unclear if that issue was related to the recently discovered zero-days.\n", "modified": "2021-01-27T12:21:28", "published": "2021-01-27T12:21:28", "id": "THREATPOST:233067E74345C95478CA096160DFCE43", "href": "https://threatpost.com/apple-patches-zero-days-ios-emergency-update/163374/", "type": "threatpost", "title": "Apple Patches Three Actively Exploited Zero-Days, Part of iOS Emergency Update", "cvss": {"score": 0.0, "vector": "NONE"}}, {"lastseen": "2021-03-02T18:06:16", "bulletinFamily": "info", "cvelist": ["CVE-2021-1782"], "description": "Hackers behind previous [iPhone jailbreak tools](<https://threatpost.com/new-ios-jailbreak-tool-works-on-iphone-models-ios-11-to-ios-13-5/156045/>) have released a jailbreak update based on a recently discovered and patched iPhone vulnerability. According to iPhone jailbreakers at UnC0ver, the tool allows users to take full control over unpatched iPhones.\n\nThe jailbreak\u2014which UnC0ver said works on iOS versions 11.0 to 14.3\u2013exploits the kernel vulnerability CVE-2021-1782, one of [three iOS flaws](<https://threatpost.com/apple-patches-zero-days-ios-emergency-update/163374/>) for which Apple released an emergency update, iOS 14.4, last month. At the time the company said the vulnerabilities potentially were being exploited in the wild.\n\nWith the release of 14.4, a number of devices already will have been updated, which means the jailbreak won\u2019t work.

Jailbreaking bypasses DRM restrictions, allowing users to run unauthorized and custom software as well as make other tweaks to iOS.\n\nApple\u2019s iOS and other OSes for its products are notoriously closed-source, which has irked developers that like to peer under the hood and play with the code on their devices. The company historically has cited security reasons for not permitting its users tinker with the proprietary code for iOS.\n\nJailbreaks like the ones unC0ver has become notorious for releasing have become popular ways for iOS developers and users to hack into their own devices to make custom changes to their devices, and are typically met with enthusiasm from iPhone aficionados.\n\n\u201cIt\u2019s great to see [#unc0ver](<https://twitter.com/hashtag/unc0ver?src=hashtag_click>) after such a long wait for a iOS 14 jailbreak on newer devices. even better that it was a complete surprise!\u201d tweeted [Jamie Bishop](<https://twitter.com/jamiebishop123>), a software engineer and self-proclaimed iOS hacker.\n\nHowever, some enthusiasts grumbled that they wish they\u2019d had prior warning that a jailbreak was going to be released, because their devices had already updated to iOS 14.4 and so the tool was rendered useless to them.\n\n\u201cWell\u2026A little heads up would\u2019ve been appreciated,\u201d [tweeted](<https://twitter.com/ddavid_son/status/1365827024774922240>) [David Davidson](<https://twitter.com/ddavid_son>), and iPhone user in Israel, in response to Bishop. \u201cNow there\u2019s a lot of us with nothing to do.\u201d\n\nIt\u2019s been a little more than 10 months since UnC0ver released its last iPhone jailbreak tool. That one came in May 2020, which allowed people to break into devices up to iOS 13.5, which was then the latest release.

In doing so, it allows iOS users to remove software restrictions imposed by Apple, thereby allowing access to additional customization and otherwise prohibited apps.\n\nFor its part, Apple has steadily made it difficult to jailbreak devices by locking down its hardware and software for security reasons, which it says helps counter malware attacks.\n\nZecOps CEO Zuk Avraham [said](<https://twitter.com/ihackbanme/status/1365862089567346689>) the jailbreak is \"yet another example that attackers have an edge on iOS vs. defenders,\" adding \"[Apple] needs to stop the need to jailbreak the device in the first place and should just enable users to have full access without a need to run an exploit.\"\n\nLast May, the unc0ver team released a [similar jailbreak](<https://thehackernews.com/2020/05/iphone-ios-jailbreak-tools.html>) for iPhones running iOS 11 to iOS 13.5 by exploiting a memory consumption issue in the kernel ([CVE-2020-9859](<https://support.apple.com/en-us/HT211214>)). But it was patched by Apple in a matter of days with the release of iOS 13.5.1 to prevent the vulnerability from being exploited maliciously.\n\n \n\n\nFound this article interesting?
