| CVE-2017-14737 | 2 Botan Project, Debian | 2 Botan, Debian Linux | 2021-12-15 | 2.1 LOW | 5.5 MEDIUM |
| A cryptographic cache-based side channel in the RSA implementation in Botan before 1.10.17, and 1.11.x and 2.x before 2.3.0, allows a local attacker to recover information about RSA secret keys, as demonstrated by CacheD. This occurs because an array is indexed with bits derived from a secret key. | |||||
| CVE-2021-40529 | 2 Botan Project, Fedoraproject | 2 Botan, Fedora | 2021-12-03 | 2.6 LOW | 5.9 MEDIUM |
| The ElGamal implementation in Botan through 2.18.1, as used in Thunderbird and other products, allows plaintext recovery because, during interaction between two cryptographic libraries, a certain dangerous combination of the prime defined by the receiver's public key, the generator defined by the receiver's public key, and the sender's ephemeral exponents can lead to a cross-configuration attack against OpenPGP. | |||||
| CVE-2018-20187 | 1 Botan Project | 1 Botan | 2019-03-12 | 4.3 MEDIUM | 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. | |||||
| CVE-2018-12435 | 1 Botan Project | 1 Botan | 2018-08-22 | 1.9 LOW | 5.9 MEDIUM |
| Botan 2.5.0 through 2.6.0 before 2.7.0 allows a memory-cache side-channel attack on ECDSA signatures, aka the Return Of the Hidden Number Problem or ROHNP, related to dsa/dsa.cpp, ec_group/ec_group.cpp, and ecdsa/ecdsa.cpp. To discover an ECDSA key, the attacker needs access to either the local machine or a different virtual machine on the same physical host. | |||||
| CVE-2016-8871 | 1 Botan Project | 1 Botan | 2016-11-29 | 2.1 LOW | 6.2 MEDIUM |
| In Botan 1.11.29 through 1.11.32, RSA decryption with certain padding options had a detectable timing channel which could given sufficient queries be used to recover plaintext, aka an "OAEP side channel" attack. | |||||
