Description Dhananjay Arunesh 2019-07-04 10:26:30 UTC
A vulnerability was discovered in ZeroMQ through 4.0.0 onwards which allows any unauthenticated client to cause a stack overflow on any server that is supposed to be protected by encryption/authentication. Arbitrary data sent by the client will overwrite the stack, so although the reporter didn't provide a specific exploit, it is entirely possible that a crafty attacker could take advantage of this vulnerability to do more than "just" crash the server.
