A local privilege escalation vulnerability was identified in the Realtek audio driver versions prior to 6.0.1.8224 in some Lenovo ThinkPad products. An attacker with local privileges could execute code with administrative privileges. Se ha identificado una vulnerabilidad de escalado de privilegios en las versiones anteriores a la 6.0.1.8224 del controlador de audio Realtek en productos Lenovo ThinkPad.

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 librería 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 tecnologías 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 característica 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 •
