If you have it on your terminals iOS 8 – iOS 8.1.2 jailbreak made using a solution released in the past for iPhone, iPad and iPod Touch by the team's hackers taiga, then I have an extremely important announcement for you.
In the solution of 8.4 iOS jailbreak a vulnerability was discovered that allows the use of the iOS setreuid function to take over administrator access and control any application to steal data from inside it, or anything else a hacker would want to steal from a terminal.
An update for the TaiG 2.xa program solved the setreuid problem at some point, but unfortunately not for those who did iOS 8 – iOS 8.1.2 jailbreak in the past, so the Chinese hackers had to create a special patch to protect them as well.
More precisely, if you have iOS 8 – iOS 8.1.2 jailbreak done on your terminals using taiga, then you will have to install a patch called TaiG 8.0-8.1.X Untethered from the repo Cydia of those from TaiG to fix this vulnerability and ensure that your data is not stolen by any person.
Users of TaiG V1.0.0-1.3.0, supporting iOS 8.0-iOS 8.1.2, don't need to rejailbreak. If you want to remove setreuid patch, add TaiG repo (res.taig.com) or 3K repo (apt.3kzhushou.com), and update TaiG 8.0-8.1.X Untether.
TaiG 8.0-8.1.X Untethered it can be installed by adding the repo to Cydia http://res.taig.com, the package being available in the latest version there, so after adding the source you will be able to install the package on your iPhone, iPad and iPod Touches to be safe.
Without this TaiG 8.0-8.1.X Untether, there is a chance that some applications can assume the role of administrator and steal important data from your terminals, so I recommend you to install it because the procedure itself is short and will not affect you in any way way.
