socat -- Heap-based buffer overflow

The socat development team reports:

This vulnerability can be exploited when socat is invoked with the READLINE address (this is usually only used interactively) without option "prompt" and without option "noprompt" and an attacker succeeds to provide malicious data to the other (arbitrary) address that is then transferred by socat to the READLINE address for output.

Successful exploitation may allow an attacker to execute arbitrary code with the privileges of the socat process.
