ESF-IDF: Heap buffer overflow in protocomm Security2 over Bluetooth
Vulnerability Description
ESF-IDF is the Espressif Internet of Things (IOT) Development Framework. In versions 5.2.6, 5.3.5, 5.4.4, 5.5.4, and 6.0, a heap buffer overflow exists in the Security Scheme 2 (SRP6a) session-setup path of the protocomm component. The first-phase handler (handle_session_command0() in components/protocomm/src/security/security2.c) trusts the length of a client-supplied protobuf field for the SRP6a username and copies it into a buffer whose size is derived from a narrower destination type. The resulting truncation-versus-copy asymmetry corrupts the heap when an oversized value is supplied. This issue has been patched in versions 5.2.7, 5.3.6, 5.4.5, 5.5.5, and 6.0.1.

ESP-IDF 安全漏洞
Vulnerability Description
ESP-IDF是Espressif开源的一个 Windows、Linux 和 macOS 上支持的 Espressif SoC 的开发框架。 ESP-IDF 5.2.6版本、5.3.5版本、5.4.4版本、5.5.4版本和6.0版本存在安全漏洞,该漏洞源于protocomm组件中安全方案2会话设置路径的堆缓冲区溢出,第一阶段处理程序信任客户端提供的protobuf字段长度并将其复制到从较窄目标类型派生的缓冲区中,导致截断与复制不对称,当提供过大值时破坏堆。
