Apple releases iOS 9.3.5 to patch serious security flaws

By , Aug 25, 2016


Apple on Thursday released iOS 9.3.5 for iPhone, iPad and iPod touch. It’s a relatively small download, weighing just 40MB, and the release notes only say that it features an “important security update.” You can install the new software via the Settings app on your iOS device, or grab it from our Download section.

Today’s update arrives 3 weeks after Apple rolled out iOS 9.3.4, which notoriously patched the latest Pangu jailbreak. Obviously, folks currently jailbroken, or those still on iOS 9.3.3 with hopes of jailbreaking should also stay away from 9.3.5, as Apple stopped signing 9.3.2 and 9.3.3 earlier this week.

Here are the full release notes from Apple’s Support page:


Available for: iPhone 4s and later, iPad 2 and later, iPod touch (5th generation) and later

Impact: An application may be able to disclose kernel memory

Description: A validation issue was addressed through improved input sanitization.

CVE-2016-4655: Citizen Lab and Lookout 


Available for: iPhone 4s and later, iPad 2 and later, iPod touch (5th generation) and later

Impact: An application may be able to execute arbitrary code with kernel privileges

Description: A memory corruption issue was addressed through improved memory handling.

CVE-2016-4656: Citizen Lab and Lookout


Available for: iPhone 4s and later, iPad 2 and later, iPod touch (5th generation) and later

Impact: Visiting a maliciously crafted website may lead to arbitrary code execution

Description: A memory corruption issue was addressed through improved memory handling.

CVE-2016-4657: Citizen Lab and Lookout

These are serious bugs, and it turns out they were being used in phone-tracking malware. Read more about the vulnerabilities here.

    It’s incredible how desperate and screwed up Apple is trying to get us to update out of ios 9.3.3, and lose our jailbreak, but NO WAY am I going to update, I’m staying put until we if and when we get an ios 10 jailbreak.

    • Apple doesn’t care about the jailbreak. Apple cares about making the most secure software. You can’t take this personally, or else you’re missing the big picture

      • Troy

        Well said Sebastian

      • JvH

        And what do you know about Apple… yep just as much as the next guy.

    • leart

      jaibreakers are 0.1 % of idevice users .. so

      • Xee

        But enough for Apple to release an update solely to ruin the last Jailbreak… just saying.

      • leart

        how you can be so obsessed with this idea.. the jailbreak was patched already with 9.3.4 and by the way that’s apples target, making iOS more secure.. the 9.3.5 it’s to patch some serious vulnerabilities that could compromise heavily the security of the device … can you imagine all celebrities, politicians, businessmans that are using Apple due of the secure echo system .. having a device that can be hacked wireless ??
        because that’s what it’s patched with 9.3.5

      • leart

        jailbreaking is dead, no community from 3-4 years now.. almost there’s no reason to jailbreak anymore

    • Diego Munhóz

      You must be kidding right ? No one cares about your Jailbreak. Those security updates are about making IOS secure. If you are willing to expose security of your information in trade off a jailbreak, it’s your choice. But take tinfoil hat out of your head… Apple world isn’t spinning around “JB users”

  • Kenneth Delgado

    With iOS 10 being in Public Beta, who in the right mind uses iOS 9 anymore?

    • Ron

      Anybody with the right mind to keep their jailbreak and the capabilities that go along with it.

    • leart

      iPhone 4s/iPad 2/iPod 5 users and who has no plan to update to iOS 10 immediately.. for example I’m not updating my 6s+ before 10.1 or when they will fix the initial bugs

    • disqus_vOL5ebQtXL

      I tried the public beta on my 6s and it was so buggy I ended up downgrading to 9.3.4

      • Christopher Lim

        beta 6 is stable enough that I can use it on my main device… plus, the only two annoying bugs I have are that third party keyboards don’t rotate properly and that mail notifications leave an empty space when dismissed… if there are any others, they aren’t obvious or in any way prevent operation. Although… feedback assistant doesn’t work for me… so… a bug in the app that’s used to report bugs…?

  • nonchalont

    Maybe a jailbreak tweak in Cydia will also fix this security hole without us having to update.

    • Hak

      9.3.4 is the only version with the security hole. So 9.0-9.3.3 and 9.3.5 are safe.

      • Rolf Bause

        No, they specifically targeted the 9.3.3 phone of this guy!

      • Sleaka J

        There is absolutely no truth to that. All versions of iOS 9 are vulnerable.

  • leart

    that tvOS profile is working perfectly .. finally my device don’t have to download and process every single ota for nothing..

  • Bugs Bunnay

    According to the verge it’s a VERY important update…

  • Jerry

    Wait for a Cydia patch update

    Apple iOS 9.3.5 Is Now Available: Why It Is An Essential Update

  • Rondog

    I think Sebastian you are one the people getting paid to send them exploits so they can patch jailbreaks. Do you work for Apple on the side?

  • Sikozu

    Has the iOS 10 Beta already got these patches in it or will we have to wait until the start of next week to get the security patch?

    Development device or not, its a pretty serious security hole to fix.

    • Sleaka J

      Only the latest Developer and Public versions of iOS10 are patched.

  • port87

    so should i stay with my jailbreak or lose it for this security patch, im conflicted.

  • Nirvana

    ruining the jailbreak or/ and secure ppl’s experience. just 2 ways down the same road. the risks of users getting hacked are much greater than jailbreak pwned.

  • rockdude094

    Does this bug exist in 8.3?

    • leart

      7.0 – 9.3.3
