Summary

Multiple stack-based buffer overflows in the SimpleBLE library for Bluetooth Low Energy. Vulnerabilities exist in the Protocol::simpleble_write function and during processing of manufacturer and service data in BLE advertisements.

Risk Assessment

An attacker can remotely (without pairing) cause a stack overflow, potentially leading to arbitrary code execution or application crash.

Recommendation

Update the SimpleBLE library to version 0.14.0 or later.

Original NVD description (English source)

SimpleBLE is a cross-platform library and bindings for Bluetooth Low Energy (BLE). Prior to version 0.14.0, there are multiple stack-based buffer overflow vulnerabilities in SimpleBLE. There is a stack overflow vulnerability in the dongl backend’s Protocol::simpleble_write function (local, caller-controlled input). A stack overflow vulnerability when processing manufacturer-specific data in BLE advertisements (remote, no pairing or connection required). Lastly, a stack overflow vulnerability when processing service data in BLE advertisements (remote, no pairing or connection required). This issue has been patched in version 0.14.0.
