Download and Install Kodi Krypton 17.3 on Your Fire TV or Stick

According the developers of Kodi at, the update from versions 17.2 Krypton is now deemed necessary due to a security issue with a malicious subtitle zip files.

Also, there are other fixes due to packaging of certain binary add-ons like PVR, visualization, and Inputstream. Apparently, they discovered it a bit late in the older releases of the Krypton media software.

So here is the list below of the fixes done in this release:

Fixes done in this release:

  • Fixed missing binary add-ons on release time
  • Fixed crash on older distros like Ubuntu 14.04 with GCC 4.8 compiler

From previous v17.2 release:

  • Fix selection after channelgroup switching in PVR guide window
  • Fix handling of gaps that caused eradic behaviour in EPG grid
  • Allow backing out of fullscreen pictures by mapping longpress guesture
  • Quick fix for wake up command not being called in PVR power management
  • Use alternative method to check if platform updates have been installed on Windows
  • Set the minimum version in the code which is currently OSX 10.8
  • Fix possible security flaw which could abused .zip files which try to traverse to a parent directory
  • Use the correct ttc font from the video file for subtitles on Windows
  • Detect and delete zero-byte database files which causes crashes

Just to be clear on the security issue, it seems that it will only affect users that have actually enabled a subtitle download and then downloaded the particular zipped subtitles. Otherwise, it seems relatively safe if you haven’t dabbled into that area.
