mbedtls: local side channel attack on classical CBC decryption in (D)TLS (CVE-2020-16150)| ID: oval:org.secpod.oval:def:1801942 | Date: (C)2021-08-02 (M)2023-03-06 |
| Class: PATCH | Family: unix |
A Lucky 13 timing side channel in mbedtls_ssl_decrypt_buf in library/ssl_msg.c in Trusted Firmware Mbed TLS through 2.23.0 allows an attacker to recover secret key information. This affects CBC mode because of a computed time difference based on a padding length.
