| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2021-09-06 | CVE-2021-40529 | Use of a Broken or Risky Cryptographic Algorithm vulnerability in multiple products 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. | 5.9 |
| 2019-03-08 | CVE-2018-20187 | Key Management Errors vulnerability in Botan Project Botan A side-channel issue was discovered in Botan before 2.9.0. | 5.9 |
| 2018-06-15 | CVE-2018-12435 | Information Exposure vulnerability in Botan Project Botan 2.5.0/2.6.0/2.7.0 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. | 5.9 |
| 2017-09-26 | 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. | 5.5 |
| 2016-10-28 | CVE-2016-8871 | Information Exposure vulnerability in Botan Project Botan 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. | 6.2 |
