| CVE-2021-40529 | 3 Botan Project, Fedoraproject, Mozilla | 3 Botan, Fedora, Thunderbird | 2024-11-21 | 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-2021-24115 | 1 Botan Project | 1 Botan | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| In Botan before 2.17.3, constant-time computations are not used for certain decoding and encoding operations (base32, base58, base64, and hex). | |||||
| CVE-2018-9860 | 1 Botan Project | 1 Botan | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in Botan 1.11.32 through 2.x before 2.6.0. An off-by-one error when processing malformed TLS-CBC ciphertext could cause the receiving side to include in the HMAC computation exactly 64K bytes of data following the record buffer, aka an over-read. The MAC comparison will subsequently fail and the connection will be closed. This could be used for denial of service. No information leak occurs. | |||||
| CVE-2018-9127 | 1 Botan Project | 1 Botan | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| Botan 2.2.0 - 2.4.0 (fixed in 2.5.0) improperly handled wildcard certificates and could accept certain certificates as valid for hostnames when, under RFC 6125 rules, they should not match. This only affects certificates issued to the same domain as the host, so to impersonate a host one must already have a wildcard certificate matching other hosts in the same domain. For example, b*.example.com would match some hostnames that do not begin with a 'b' character. | |||||
| CVE-2018-20187 | 1 Botan Project | 1 Botan | 2024-11-21 | 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 | 2024-11-21 | 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-2017-7252 | 1 Botan Project | 1 Botan | 2024-11-21 | N/A | 7.5 HIGH |
| bcrypt password hashing in Botan before 2.1.0 does not correctly handle passwords with a length between 57 and 72 characters, which makes it easier for attackers to determine the cleartext password. | |||||
