Impact

Converting a GDB registers profile file into a Rizin register profile can result in a stack-based buffer overflow when the name, type or groups fields have longer values than expected. Users opening untrusted GDB registers files (e.g. with the drpg or arpg commands) are affected by this flaw.

Patches

#3422
d619670

Workarounds

Review the GDB register profiles before loading them with drpg/arpg commands.
