While processing a new image, the Firmware Upgrade (FWU) module does not validate the length field of the Type-Length-Value (TLV) structure for dependent components against the maximum allowed size. If the length specified in the TLV exceeds the size of the buffer allocated on the stack, the FWU module will overwrite the buffer (and potentially other stack data) with the TLV's value content. An attacker could exploit this by crafting a malicious TLV entry in the unprotected section of the MCUBoot upgrade image. By setting the length field to exceed the expected structure size, the attacker can manipulate the stack memory of the system during the upgrade process."}, {"lang": "es", "value": "TrustedFirmware-M (tambi\u00e9n conocido como Trusted Firmware for M profile Arm CPUs) en versiones anteriores a la 2.1.3 y 2.2.x anteriores a la 2.2.1 carece de validaci\u00f3n de longitud durante una actualizaci\u00f3n de firmware. Al procesar una nueva imagen, el m\u00f3dulo Firmware Upgrade (FWU) no valida el campo de longitud de la estructura Type-Length-Value (TLV) de los componentes dependientes con respecto al tama\u00f1o m\u00e1ximo permitido.
