CVE-ID : CVE-2020-16150
Package : mbedtls
Type : private key recovery
Remote : No
Link : https://security.archlinux.org/AVG-1386
The package mbedtls before version 2.25.0-1 is vulnerable to private
key recovery.
Upgrade to 2.25.0-1.
The problem has been fixed upstream in version 2.25.0.
None.
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. The
issue is fixed in Mbed TLS 2.24.0, 2.16.8 and 2.7.17.
An attacker might be able to recover secret key information via a side-
channel.
