CVE-2023-27590 Information

Description

Rizin is a UNIX-like reverse engineering framework and command-line toolset. In version 0.5.1 and prior 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. Commit d6196703d89c84467b600ba2692534579dc25ed4 contains a patch for this issue. As a workaround review the GDB register profiles before loading them with drpg/arpg commands.
