Josef Gajdusek discovered that OpenOCD, a JTAG debugger for ARM and MIPS, was vulnerable to Cross Protocol Scripting attacks. An attacker could craft a HTML page that, when visited by a victim running OpenOCD, could execute arbitrary commands on the victims host.
This fix also sets the OpenOCD default binding to localhost, instead of every network interfaces. This can be changed with the added 'bindto’command argument.
