CVE-2019-14853
An error-handling flaw was found in python-ecdsa. During signature decoding, malformed DER signatures could raise unexpected exceptions or no exceptions at all, which could lead to a denial of service...
Amazon Linux 2 : nss (ALAS-2019-1305)
A cached side channel attack during handshakes using RSA encryption could allow for the decryption of encrypted content. This is a variant of the Adaptive Chosen Ciphertext attack AKA Bleichenbacher attack and affects all NSS versions prior to NSS 3.41. CVE-2018-12404 Libgcrypt before 1.7.10 and...
CVE-2019-15809
Smart cards from the Athena SCS manufacturer, based on the Atmel Toolbox 00.03.11.05 and the AT90SC chip, contain a timing side channel in ECDSA signature generation. This allows a local attacker, able to measure the duration of hundreds to thousands of signing operations, to compute the private...

CVE-2019-13629
MatrixSSL 4.2.1 and earlier contains a timing side channel in ECDSA signature generation. This allows a local or a remote attacker, able to measure the duration of hundreds to thousands of signing operations, to compute the private key used. The issue occurs because crypto/pubkey/eccmath.c scalar...

CVE-2019-13629
CVE-2019-13629 affects MatrixSSL 4.2.1 and earlier. The vulnerability is a timing side channel in ECDSA signature generation: the implementation leaks the bit length of the scalar via scalar multiplication in crypto/pubkey/ecc_math.c. An attacker who can observe durations over hundreds to thousan...
