CVE-2017-15361
https://notcve.org/view.php?id=CVE-2017-15361
The Infineon RSA library 1.02.013 in Infineon Trusted Platform Module (TPM) firmware, such as versions before 0000000000000422 - 4.34, before 000000000000062b - 6.43, and before 0000000000008521 - 133.33, mishandles RSA key generation, which makes it easier for attackers to defeat various cryptographic protection mechanisms via targeted attacks, aka ROCA. Examples of affected technologies include BitLocker with TPM 1.2, YubiKey 4 (before 4.3.5) PGP key generation, and the Cached User Data encryption feature in Chrome OS. La librerÃa Infineon RSA 1.02.013 en firmware Infineon Trusted Platform Module (TPM) como las versiones anteriores a la 0000000000000422 - 4.34, anteriores a la 000000000000062b - 6.43 y anteriores a la 0000000000008521 - 133.33, gestiona de manera incorrecta la generación de claves RSA, lo que hace que sea más fácil para los atacantes superar varios mecanismos de protección criptográfica mediante ataques dirigidos, conocido como ROCA. Ejemplos de las tecnologÃas afectadas son BitLocker con TPM 1.2, la generación de claves PGP con YubiKey 4 (en versiones anteriores a la 4.3.5) y la caracterÃstica de cifrado Cached User Data en Chrome OS. • https://github.com/nsacyber/Detect-CVE-2017-15361-TPM https://github.com/lva/Infineon-CVE-2017-15361 https://github.com/Elbarbons/ROCA-attack-on-vulnerability-CVE-2017-15361 http://support.lenovo.com/us/en/product_security/LEN-15552 http://www.securityfocus.com/bid/101484 https://arstechnica.com/information-technology/2017/10/crypto-failure-cripples-millions-of-high-security-keys-750k-estonian-ids https://blog.cr.yp.to/20171105-infineon.html https://cert-portal.siemens.com/productcert/pdf •
CVE-2017-3756
https://notcve.org/view.php?id=CVE-2017-3756
A privilege escalation vulnerability was identified in Lenovo Active Protection System for ThinkPad systems versions earlier than 1.82.0.17. An attacker with local privileges could execute code with administrative privileges via an unquoted service path. Se identificó una vulnerabilidad de escalado de privilegios en Lenovo Active Protection System para versiones de sistemas ThinkPad anteriores a la 1.82.0.17. Un atacante con privilegios locales podría ejecutar código con privilegios de administrador a través de una ruta de servicio sin entrecomillar. • http://www.securityfocus.com/bid/100305 https://support.lenovo.com/us/en/product_security/LEN-15765 •
CVE-2016-8222
https://notcve.org/view.php?id=CVE-2016-8222
A vulnerability has been identified in a signed kernel driver for the BIOS of some ThinkPad systems that can allow an attacker with Windows administrator-level privileges to call System Management Mode (SMM) services. This could lead to a denial of service attack or allow certain BIOS variables or settings to be altered (such as boot sequence). The setting or changing of BIOS passwords is not affected by this vulnerability. Una vulnerabilidad ha sido identificada en un controlador de kernel firmado para la BIOS de algunos sistemas ThinkPad que pueden permitir a un atacante con privilegios nivel administrador de Windows llamar a servicios System Management Mode (SMM). Esto puede conducir a un ataque de denegación de servicio o permitir que ciertas variables o ajustes BIOS sean alterados (como una secuencia boot). • http://www.securityfocus.com/bid/94409 https://support.lenovo.com/us/en/solutions/LEN_8327 • CWE-284: Improper Access Control •
