LG G3 'Snap' Vulnerability Leaves Owners At Risk of Data Theft (betanews.com)

Mark Wilson writes: Security researchers have discovered a vulnerability in LG G3 smartphones which could be exploited to run arbitrary JavaScript to steal data. The issue has been named Snap, and was discovered by Israeli security firms BugSec and Cynet. What is particularly concerning about Snap is that it affects the Smart Notice which is installed on all LG G3s by default. By embedding malicious script in a contact, it is possible to use WebView to run server side code via JavaScript. If exploited, the vulnerability could be used to gather information from SD cards, steal data from the likes of WhatsApp, and steal private photos.

      And this is why LG is losing me as a customer. They drag their feet with every single security update, probably to "encourage" owners to upgrade. You'd think that they could afford to hire someone just to take care of the occasional security patch and update. That and they should be sued for their phones overheating because of the 810 processor. As good as the LG G4's camera is, Samsung's is on par with it and other's are catching up as well.

      My G4 has been running marshmallow from the carrier's ota update for close to a month, it was one of the first phones in the states to get it. My G3 before it also got lollipop very quick, among the first phones to get it as well. The G4 uses the snapdragon 808, not 810, by the way. I used to be a Samsung user until I broke my galaxy s4 and decided to try out LG... I was tired of touchwiz, tired of the physical home button and capacitive keys... When I broke my galaxy s4, I looked at YouTube videos on repairing the screen... It looked like a nightmare- the glass is glued to the amoled display, you need a heat gun to soften it up enough to pry the glass off. I recently broke the screen on my G4, watched a video on how to repair and was surprised how simple it was... Ordered the replacement and when it arrived had it switched out and phone running in under 15 minutes, didn't even have to watch the video again to do it. It's also survived a drop into a full bathtub. I'm a very satisfied customer and imagine my next phone will be the G5 or possibly the V10 successor. Not a paid shill, just can't sign out of this damned account to my original one. ~jsh1972

    Exactly, that's a nice list of patched vulnerabilities. Every one of those seems to be present in versions prior 9.2.

    Considering that the most prevalent version of Android is 4.4 Kit Kat, released in September 2013, this is also why I have an iPhone.

    While the G3 may (or may not) get an update to that specific piece of software, there are no guarantees. A similar vulnerability in an iOS would definitely be patched in the newest update.

    This is, again, why I have an iPhone

    Yes, because no iphone has ever had a security vulnerability, now or in the future. It's impossible, IOS is simply impossible to hack, spoof, or do anything bad to, ever. It just can't be done, there is no way to do it. No one has ever hacked an IOS device and no one ever will. Ever. It's just completely out of the question. The words "vulnerability" and "IOS" should never even be found in the same paragraph, let alone the same sentence. IOS has never had a security vulnerability and never will, updates are strictly there to add exciting new features. Everyone knows that.

    This is also why I only have a Nexus, most of these security issues are with third party android handsets with most never getting timely updates (Google really needs to fix this issue). I buy a Nexus for the same reason you get an iphone, up_to_date_security_patches. Yes many of you will say "but, but you can use xyz third party android roms and they don't have this issue". The issue with that is android is now mainstream so 98% of android device owners do not have the ability or the knowledge to change the firmware. The fix is simple, Google needs to start enforcing better security policies on companies who want too use the Google android(tm) brand. People are just going to get sick of not having updates and move to GASP! Windows or Apple.

    That's two words and an up to date CM isn't available for every phone. The version available for my old Note 2 for example is based on KitKat. Even if CM supported every phone 100% that's still no excuse for the manufacturers to abandon their customers. The Note 2 was an expensive flagship phone. It should be getting the same kind of support that iPhones get. That's why I abandoned Android. The only Nexus available at the time was a ridiculously huge 6in one and I wanted one below 5in. For a high spec phone that left me two options: Apple or Sony and I didn't have any faith that Sony would update their handset in a reasonable time.

    To be fair, your KitKat Note 2 is using the latest Chromium webview that even Android Marshmallow is using (because Google is doing an end-run around the manufacturer updates for some of its component updates).

    I'm not sure why the LG G3 is not doing the same with SmartNotice. It looks like LG G3 is purposefully going out of its way not to use it for its SmartNotice functionality, despite the fact that it is indeed using the right most-up-to-date version of webview for everything else.

    Your point is irrelevant. Apple fixes its bugs and provides updates to devices that are over 4 years old. How many 4 year old Android phones are on Marshmallow? My old Note 2 from by far the biggest Android OEM is still on KitKat. I like Android but the fragmentation situation is ridiculous. Just buy a Nexus is a crap answer as well.

    And that one too. I can do this all day. Where's the security fixes for my old Note 2 which is newer than the iPhone 4s? Nowhere in sight unless I install a ROM that may or may not support my hardware. The Android ecosystem sucks hard, regardless of the merits of the OS itself (which I like and use). I don't know why you're so ardently defending Samsung / HTC / Sony et al when they don't give a shit about your security. Apple are a bunch of scumbags, but a bunch of scumbags that actually fix their software, rather than leaving their users hanging out to dry.
