+| [CVE-2019-15809](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-15809) | Athena IDProtect | | 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 key used. The issue occurs because the Atmel Toolbox 00.03.11.05 contains two versions of ECDSA signature functions, described as fast and secure, but the affected cards chose to use the fast version, which leaks the bit length of the random nonce via timing. This affects: <ul> <li>Athena IDProtect 010b.0352.0005</li> <li>Athena IDProtect 010e.1245.0002</li> <li>Athena IDProtect 0106.0130.0401</li> <li>Athena IDProtect 010e.1245.0002</li> <li>Valid S/A IDflex V 010b.0352.0005</li> <li>SafeNet eToken 4300 010e.1245.0002</li> <li>TecSec Armored Card 010e.0264.0001</li> <li>TecSec Armored Card 0108.0264.0001</li> </ul> | [Jan Jancar](https://github.com/J08nY) |

+|:-------------------------------------------------------------------------------:|:------------------------:|:---------:| ----------- |:----------:|
+| [CVE-2018-20187](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-20187) | Botan 2 | 5.9 MEDIUM| A side-channel issue was discovered in Botan before 2.9.0. An attacker capable of precisely measuring the time taken for ECC key generation may be able to derive information about the high bits of the secret key, as the function to derive the public point from the secret scalar uses an unblinded Montgomery ladder whose loop iteration count depends on the bitlength of the secret. This issue affects only key generation, not ECDSA signatures or ECDH key agreement.| [Jan Jancar](https://github.com/J08nY)|
+| [CVE-2019-13627](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-13627) | libgcrypt | 5.9 MEDIUM| Libgcrypt 1.3.0 through 1.8.4 (ECDSA) and 1.6.0 through 1.8.4 (EdDSA) contains a timing side channel in ECDSA/EdDSA 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 mpi/ec.c scalar multiplication leaks the bit length of the scalar.| [Jan Jancar](https://github.com/J08nY)|
+| [CVE-2019-13628](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-13628) | wolfCrypt, wolfSSL | 5.9 MEDIUM| wolfSSL and wolfCrypt 4.0.0 and earlier (when configured without --enable-fpecc, --enable-sp, or --enable-sp-math) contain a timing side channel in ECDSA signature generation. This allows a local attacker, able to precisely measure the duration of signature operations, to infer information about the nonces used and potentially mount a lattice attack to recover the private key used. The issue occurs because ecc.c scalar multiplication might leak the bit length.| [Jan Jancar](https://github.com/J08nY)|
+| [CVE-2019-13629](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-13629) | MatrixSSL | 5.9 MEDIUM| 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/ecc_math.c scalar multiplication leaks the bit length of the scalar.| [Jan Jancar](https://github.com/J08nY) |
+| [CVE-2019-14318](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-14318) | Crypto++ | 5.9 MEDIUM| Crypto++ 8.3.0 and earlier contains a timing side channel in ECDSA signature generation. This allows a local or remote attacker, able to measure the duration of hundreds to thousands of signing operations, to compute the private key used. The issue occurs because scalar multiplication in ecp.cpp (prime field curves, small leakage) and algebra.cpp (binary field curves, large leakage) is not constant time and leaks the bit length of the scalar among other information.| [Jan Jancar](https://github.com/J08nY)|
