Is there a security ssh issue in ubuntu?

Asked by Daniel Stone

We have limited information about this exploit and the extent of it, but as far as we know, it affects only Linux boxes running OpenSSH compiled against OpenSSL, with the exception of OpenSSL version 1.0.x beta.

Is this resolved in any patches?

There are indeed rumors about security problems in ssh. However nobody was able to verify them:

If you have more information, you should indeed submit more info - but at this time there is no reason to worry.

From what I can gather I can ask an answer my own question. This effects CentOS and only ver. 4.3 ssh. Yes this is a security issue. Many refer to it as 0day or Oday.
Here is a link to more info
As I know little of ssh I do heed a warning because my host(which is said to host 1.8 million domains) is changing their ssh.
can somone look into this...

According to everything I have read, this has not been confirmed to be anything more than a hoax. That is not to say that such a exploit does not exist, but simply that I have not seen one reliable source that can confirm such an exploit.

Obviously the best way to stay secure is to ensure you are receiving all of the latest updates. If a security flaw is confirmed it will most certainly be reported here:

Can you help with this problem?
