Arch Linux Security Advisory ASA-202007-5
Date : 2020-07-31
CVE-ID : CVE-2020-10932
Package : mbedtls
Type : private key recovery
Remote : No
Link : https://security.archlinux.org/AVG-1141
The package mbedtls before version 2.16.7-1 is vulnerable to private
Upgrade to 2.16.7-1.
# pacman -Syu "mbedtls>=2.16.7-1"
The problem has been fixed upstream in version 2.16.7.
A side channel attack has been found on the ECDSA implementation of
Mbed TLS before 2.22.0, 2.16.6 and 2.7.15, allowing a local attacker
with access to precise enough timing and memory access information
(typically an untrusted operating system attacking a secure enclave
such as SGX or the TrustZone secure world) to fully recover an ECDSA
private key after observing a number of signature operations.
A remote attacker is able to recover an ECDSA private key.
