Hi Steve, vendors,

longer than 512 bytes. An attacker, able to to inject data into sockat's command line
(potentially remotely via CGI script invocation), could use this flaw to execute
arbitrary code with the privileges of the socat process.


Upstream patch against v1.7.2:

Thanks && Regards, Jan.
