CVE-2017-7252 |
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. Published: November 02, 2023; 9:15:07 PM -0400 |
V3.1: 7.5 HIGH V2.0:(not available) |
CVE-2021-40529 |
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. Published: September 06, 2021; 3:15:07 PM -0400 |
V3.1: 5.9 MEDIUM V2.0: 2.6 LOW |
CVE-2021-24115 |
In Botan before 2.17.3, constant-time computations are not used for certain decoding and encoding operations (base32, base58, base64, and hex). Published: February 21, 2021; 9:15:14 PM -0500 |
V3.1: 9.8 CRITICAL V2.0: 7.5 HIGH |
CVE-2018-20187 |
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. Published: March 08, 2019; 2:29:00 PM -0500 |
V3.0: 5.9 MEDIUM V2.0: 4.3 MEDIUM |
CVE-2018-9860 |
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. Published: April 12, 2018; 1:29:00 AM -0400 |
V3.0: 7.5 HIGH V2.0: 5.0 MEDIUM |
CVE-2017-14737 |
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. Published: September 25, 2017; 9:29:03 PM -0400 |
V3.1: 5.5 MEDIUM V2.0: 2.1 LOW |
CVE-2016-9132 |
In Botan 1.8.0 through 1.11.33, when decoding BER data an integer overflow could occur, which would cause an incorrect length field to be computed. Some API callers may use the returned (incorrect and attacker controlled) length field in a way which later causes memory corruption or other failure. Published: January 30, 2017; 5:59:00 PM -0500 |
V3.0: 9.8 CRITICAL V2.0: 7.5 HIGH |
