Samsung Tizen Security Holes

Tizen OS Logo

Amihai Neiderman, head of research at Israel-based Equus Technologies, discovered 40 not yet publicly disclosed vulnerabilities that could allow a remote hack of Samsung gear running its Tizen operating system: smart TVs, Gear smartwatches, and smartphones. Samsung plans to use Tizen on its washing machines and refrigerators, too. One particularly critical vulnerability called a heap-overflow vulnerability involves Samsung’s TizenStore app: Neiderman was able to hijack the app and deliver malicious code to his Samsung TV. All Tizen OS-based devices connect to the TizenStore to receive apps and app updates; a vulnerability there could mean malicious code can be easily sent to millions of devices running the Tizen operating system.

Neiderman contacted Samsung months ago regarding the vulnerabilities but received only an automated email response. Now, after publication of Neiderman’s foundings, Samsung has responded that the company will be working with the researcher to patch vulnerabilities.

Samsung Smart TV Tizen OS

Fixing Tizen will most likely take some time, so while we are waiting let’s make sure to cut internet connectivity on any Tizen-based gear we might have, just to be safe: Samsung’s TVs (4K SUHD TV, 4K UHD TV, LED TV), smartphones (Z1, Z2, Z3), wearables (Gear S, Gear 2, Gear 2 NEO, Gear S2, Gear S3), etc. TVs can easily be viewed without a direct internet connection since there are many devices such as Apple TV, ChromeCast, Roku, etc., and Gear watches can be used simply as a watch, but Tizen smartphones will realistically become useless, unless Samsung works quickly to patch all of Tizen’s vulnerabilities.

LG Signature OLED TV W

LG Signature OLED W7 TV

The LG Signature OLED TV W series is a 4K OLED TV with HDR, but so thin and light it attaches to the wall using magnets.

The OLED TV itself has a dimension of 67.8×38.9×0.2 inches. Yes, that’s just 0.2 inches (0.51 cm) thick. 76.7 inches worth of OLEDs only weighs 27.1 pounds (12.3 kg). The AV Box weighs more: 28.0 pounds.

Technical Specifications:

  • Display: 76.7-inch (194.8 cm) 3840×2160 OLED
  • HDR: Dolby Vision, HDR10, HLG
  • Sound: Dolby Atmos / DTS-HD, 4.2 Channel, 60W
  • Wireless: 802.11ac
  • Ports: 4x HDMI (HDCP 2.2), 3x USB-A, 1x RF-in, 1x Composite-in, 1x Component-in, 1x Ethernet, 1x Optical, 1x RS-323C (Mini Jack)
  • OS: webOS 3.5

I think LG should have done what Sony did: get rid of the speakers. (Perhaps that sonic technology was too thick?) What’s the use of a 0.2-inch thick OLED TV when the AV Box protrudes out 8.2 inches. For customers who want the absolute minimal, thinnest OLED TV there are plenty of in-wall speaker solutions to completely hide everything except for the display.

Sony A1

Sony A1 / A1E OLED TV

The Sony A1 series — the series name for the US versions is A1E — is a 4K Ultra HD (UHD) OLED Smart Android TV with High Dynamic Range (HDR).

Minimal, is the perfect word to describe Sony’s A1: an OLED display panel, protected by a cover glass, encased in a metal frame. Sony’s Acoustic Surface generates sound by vibrating the screen, in lieu of traditional speakers. A stand props up the beautiful display.

Initial reports seem to suggest the Sony A1 is easily the brightest OLED on the market, and indicate LG Display as the OLED panel supplier.

Technical Specifications:

  • Display: 55, 65, 77 UHD OLED
  • HDR: Dolby Vision, HDR10
  • Visual Engine: X1 Extreme
  • OS: Android TV

Android. I think it would have been better to leave out an operating system. The SoC, RAM, storage, etc. will all be in need of upgrading in the next two to three years. I would not want to be forced to upgrade my TV in a couple of years just because the computer parts are getting old. Leave the OS stuff to external boxes; they are cheap and better ones come out frequently.

The OLED TV market is getting some competition and that should make OLED TVs better, more affordable, and soon.
