Arm Mbed TLS before 2.16.5 allows attackers to obtain sensitive information (an RSA private key) by measuring cache usage during an import. Arm Mbed TLS versiones anteriores a 2.16.5, permite a atacantes obtener información confidencial (una clave privada RSA) al medir el uso de la memoria caché durante una importación. • https://lists.debian.org/debian-lts-announce/2022/12/msg00036.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5JPE2HFBDJF3UBT6Q4VWLKNKCVCMX25J https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WD6OSOLLAR2AVPJAMGUKWRXN6477IHHV https://tls.mbed.org/tech-updates/security-advisories/mbedtls-security-advisory-2020-02 •

The ECDSA signature implementation in ecdsa.c in Arm Mbed Crypto 2.1 and Mbed TLS through 2.19.1 does not reduce the blinded scalar before computing the inverse, which allows a local attacker to recover the private key via side-channel attacks. La implementación de la firma ECDSA en el archivo ecdsa.c en Arm Mbed Crypto versión 2.1 y Mbed TLS versiones hasta 2.19.1, no reduce el escalar ciego antes de calcular el inverso, lo que permite a un atacante local recuperar la clave privada por medio de ataques de canal lateral. • https://lists.debian.org/debian-lts-announce/2022/12/msg00036.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/A3GWQNONS7GRORXZJ7MOJFUEJ2ZJ4OUW https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NGDACU65MYZXXVPQP2EBHUJGOR4RWLVY https://tls.mbed.org/tech-updates/security-advisories https://tls.mbed.org/tech-updates/security-advisories/mbedtls-security-advisory-2019-12 • CWE-203: Observable Discrepancy •

Arm Mbed TLS before 2.19.0 and Arm Mbed Crypto before 2.0.0, when deterministic ECDSA is enabled, use an RNG with insufficient entropy for blinding, which might allow an attacker to recover a private key via side-channel attacks if a victim signs the same message many times. (For Mbed TLS, the fix is also available in versions 2.7.12 and 2.16.3.) Arm Mbed TLS versiones anteriores a 2.19.0 y Arm Mbed Crypto versiones anteriores a 2.0.0, cuando el ECDSA determinista está habilitado, usa un RNG con entropía insuficiente para el cegamiento, lo que podría permitir a un atacante recuperar una clave privada por medio de ataques de canal lateral si una víctima firma el mismo mensaje muchas veces. (Para Mbed TLS, la corrección también está disponible en las versiones 2.7.12 y 2.16.3.) • https://github.com/ARMmbed/mbedtls/commit/298a43a77ec0ed2c19a8c924ddd8571ef3e65dfd https://github.com/ARMmbed/mbedtls/commit/33f66ba6fd234114aa37f0209dac031bb2870a9b https://lists.debian.org/debian-lts-announce/2022/12/msg00036.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CGSKQSGR5SOBRBXDSSPTCDSBB5K3GMPF https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CSFFOROD6IVLADZHNJC2LPDV7FQRP7XB https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproje •
