Security experts have poured cold water on an OpenSSL vulnerability which a group of hackers have dubbed Heartbleed 2. A group of five hackers claimed on Pastebin that they have discovered another major security flaw in OpenSSL. They said they had found an vulnerability in the patched version OpenSSL. A missing bounds check in the handling of the variable DOPENSSL_NO_HEARTBEATS.
“We could successfully Overflow the DOPENSSL_NO_HEARTBEATS and retrieve 64kb chunks of data again on the updated version," they said.
The hackers said they would not make the vulnerability public as it would only allow companies to patch the flaw. They added they could exploit the flaw themselves "for a long time" before it gets patched, but they are also willing to sell it for $1,085.
"We are team of five people, and we have coded nonstop for 14 days to see if we could find a workaround, and we did it! We have no reason to make it public when the vendors will go for a update again," the group said.
The only evidence given that the vulnerability is realise this image of what appears to be the output from a server to a request from the attackers. However Security experts have pointed out that the DOPENSSL_NO_HEARTBEATS variable mentioned by the hackers doesn't actually exist.
