VAR-201909-1025
Vulnerability from variot - Updated: 2023-12-18 13:07On STMicroelectronics STM32L0, STM32L1, STM32L4, STM32F4, STM32F7, and STM32H7 devices, Proprietary Code Read Out Protection (PCROP) (a software IP protection method) can be defeated by observing CPU registers and the effect of code/instruction execution. plural STMicroelectronics Product devices contain unauthorized authentication vulnerabilities.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Security vulnerabilities exist in several STMicroelectronics products. An attacker could exploit this vulnerability to bypass proprietary Code Readout Protection (PCROP). The following products and versions are affected: STMicroelectronics STM32L0; STM32L1; STM32L4; STM32F4; STM32F7; STM32H7
