MC-78113 Disconnecting after death on hardcore mode server does not close connection to server Awaiting Response MC-77548 Major - Impossible to get the EXACT block player is standing on Duplicate

Comments

Sorry can confirm this fixes nothing at all. All issues mentioned in previous comments are displayed in snapshot 15w37a.

It might even be worse, single player no longer deletes the world even if you press delete.

If the player "x's" out after death the server still holds the player connection.

Also in single player if I try to create a new world after a death HC mode this is displayed. See screen shot attached

EDIT: All testing done using 100% vanilla MC running 64bit windows 7

Hope this helps.

Showing the screen in snapshot 15w37a when you try and create a new world if previous world was hardcore and player died.

One thing I will test in the snapshot is what if the player doesn't select either option and just "X's" out of the client completely. Hopefully the server doesn't hold on to a connection or even what it thinks is a connection and the player still appearing in the scoreboard etc. Will report back give me 5 mins.

Ok thks

Only got them after posting.

Snapshot can't be evidence of it being fix as by its very nature a snapshot's are subject to change at any point. As this is an old bug until there is a release version with this fixed surely it should stay open. I will test the snapshot if you like to see if that is fixed "in" that snapshot.

Tested in multiplayer and does not switch player to spectator mode on death, if it does it makes no difference to the bug described here. Bug confirmed in 1.8.8 Vanilla SMP.

Please re open this is not fixed at all.

This is not fixed, try single player mode, die and you can still hear all the game sounds in the main menu when ejected from the game. Tested using the latest 1.8.8 100% vanilla MC.

Makes no difference if you join a plugin server or a standard MC MP server the same issues occur. Tested in 1.8.4 as well and its still the same. Such a dangerous issue this if you know what your doing with packets.

This is not a duplicate issue to mine reported at MC-78113 as my issue CAN NOT be created in clients below 1.8.3 unlike what is described here. Related maybe but not a duplicate.

Can confirm this issue is 100% your issue just play hardcore mode on vanilla mc server and you can create the same results. Oh also confirm i can change I can run any command I like on the server you start with if you own the 2nd server surprising what a few packets sent back can do... err did i say force o.......

Disgrace I reported this near 2 months ago.

Well i take my hat off to you guys, you deserve a medal if you do what you do for the love of the Job. I do just the same as you i do a lot of stuff for no money and the love of it, just not for a corporate, but won't go down the road. If I have access to various code bases, the least you guys should to. Are you guys from a developers back ground ? Only asking as if it was this should of been resolved the day i reported it, its that big of a security breach. I don't expect some instance response for standard issues, but some related to security breaches is different. So when I see nothing no responses of any real meaning or signs of progress I'll just keep on posting.

Still end of the day the massive security hole is open and fingers crossed you don't end up liable as its been reported to you. When I say you I mean Mojang not you guys personally.

I'll try tweeting it to the devs and see if somebody can do something about this,

Am not laughing at you guys or your reasoning for doing what you but a $2,5Billion company uses free labor to deal with their tickets and doesn't provide you with the code to be able to investigate things fully either, What I imagine was this was set up years ago and nothing has changed.

Not sure how to take your last reply, I will ignore the tone and just give you a reply. "You need to sort this" , "you" as in mojang, its a massive security breach and un suspected server owners find they have all these players connected to the server that don't seen to exist. Plus this is so open to abuse its unreal I can crash players "in theory" shouldn't be connected to my server, I can get that player to say stuff in chat on the other server. When I say my server I use the term generally as I only develop for people, and all testing has been done discreetly with my own accounts. There is also other things that can be done with you know what your doing, I shan't list them as I do not wish for that part to become public knowledge.

Tell me this is WAI , as clearly you have no sense or urgency to patch this massive hole.

I'll leave you to it and do the next best thing and let all the owners know about this breach so they can at least try to deal with any consequences that it may cause them. Oh look though your 2K un resolved issues and your find somebody actually reported this same thing to you 5 weeks ago but no body even bothered to reply. I say unresolved , there all the unanswered issues which doesn't show up as unresolved issues, funny that.

Don't expect me ever to report issue again I spent days trying to find the cause so you guys wouldn't have to to, hmm can you force op with this breach ??? Investigate it and your find the answer to that question.

Yes bungee is NOT needed to create this issue. It can be to 2 single servers on different ip's any where in the world owned by completely separate people.

I server owner can potential cause a player to crash when there on somebody else's server by sending a corrupt packet on purpose. Or play tricks by sending ghost blocks which would seem like it was real to the unsuspecting player. until they click on them..

Oh another thing when the player leaves player A, all sound from the server will still be heard when not logged into any server, by the I mean in the MP server selection list in the client.

From hours of research I personally feel I could find a way to crash Server B. Hmm just thought I wonder if I can get player to speak in Server B's chat and have it appear to other players on server B.

I will not be doing anything to on a public server all testing is done of private servers i own, the only purpose is to discover the seriousness of this issue and it should be being looked into with the highest priority.as this is a big Security issue either way you look at it Server being able to be connected to players on other servers .

I must of spent over 50 hours investigating this issue,, not on the cause but of the possible potential of being a serious concern that warrants all server owners knowing about so they could take action, eg block .1.8.3 client from logging into their servers. I do hope a dev is assigned to investigate very soon as this is already 4 days old and it still is assigned to anybody.

Hi

Again you not actual seeing the end result. I am fully aware of the math, the reason I did 2 blocks up was to allow for the player to still be stood there and not have the block place in his head.

Ok looking at my last image tell me which block do you think i am stood on ? Diamond or stone ? I am not debating the math here I agree with everything you have said BUT its the outcome in game.

Which block would I need to delete to make my player drop down into the hole left ?? Bare in mind it must be either the diamond or the stone ?? I will provide you with video evidence once you tell me that is the correct intended outcome. It may well surprise you. Bare also that if i do /setworldspawn from where I am at, the spawn will be the center of the stone, so mc is saying internally I am stood on the stone block.

Regards

Are you going to change the status of this issue as I have proved it clearly has nothing to do with the TP issues.

Here is another using whole numbers same result !!

Sorry but you theory is invalid. See this screen shot. All cords are positive including direction and this time I am setting the block 2 blocks above. Same result.

See the incorrect rounding of the X co-ord 112.938 to 112 hmmm

Please re open this not teleport specific at all. OR are you telling me this is intended

Edit: To clarify my aim is nothing to do with setblocks my issue is you are unable to test for what block a player is standing on. If I want to trigger an event when a player moves over a certain block, You will be get false triggers due to this bug.

This is not a duplicate. This works on flat ground, I used the example on a block to make it easier to see.

Now please explain why the same effect happens with positive cords ???

Why does 84.686 get round to 84 for the z access. I can stand and face any direction with the same result. This is not intended results. I understand the negative cords but positive to. Are you telling me that it is intended to allow the player location to be 1 or 9 different blocks. Please don't say just stand back from the edge as when your testing for the abstract with no prior knowledge to where a player is, it is impossible to get a true location, this has huge effects on every part of the game.

Please reopen

Thanks
