| CVE-2026-44378 | Hig | 0.42 | 7.5 | 0.00 | May 27, 2026 | Botan is a C++ cryptography library. Prior to 3.12.0, certain patterns of indefinite length encodings in BER data could cause quadratic behavior in the parser, resulting in a denial of service. Such BER encodings were accepted even in structures which are required to be encoded… | ||
| CVE-2024-34703 | Hig | 0.42 | 7.5 | 0.01 | Jun 30, 2024 | Botan is a C++ cryptography library. X.509 certificates can identify elliptic curves using either an object identifier or using explicit encoding of the parameters. Prior to versions 3.3.0 and 2.19.4, an attacker could present an ECDSA X.509 certificate using explicit encoding… | ||

A specially crafted X509 certificate would need to be delivered to the client or server… | ||
| CVE-2016-8871 | Med | 0.40 | 6.2 | 0.00 | Oct 28, 2016 | 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. | ||
| CVE-2017-14737 | Med | 0.36 | 5.5 | 0.00 | Sep 26, 2017 | 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… | ||
| CVE-2026-32884 | Med | 0.31 | 5.9 | 0.00 | Mar 30, 2026 | Botan is a C++ cryptography library. Prior to version 3.11.0, during processing of an X.509 certificate path using name constraints which restrict the set of allowable DNS names, if no subject alternative name is defined in the end-entity certificate Botan would check that the… | ||
| CVE-2026-32883 | Med | 0.31 | 5.9 | 0.00 | Mar 30, 2026 | Botan is a C++ cryptography library. From version 3.0.0 to before version 3.11.0, during X509 path validation, OCSP responses were checked for an appropriate status code, but critically omitted verifying the signature of the OCSP response itself. This issue has been patched in… | ||
| CVE-2024-34702 | Med | 0.27 | 5.3 | 0.01 | Jul 8, 2024 | Botan is a C++ cryptography library. X.509 certificates can identify elliptic curves using either an object identifier or using explicit encoding of the parameters. Prior to 3.5.0 and 2.19.5, checking name constraints in X.509 certificates is quadratic in the number of names… | ||
| CVE-2024-50382 | 0.00 | — | 0.01 | Oct 23, 2024 | Botan before 3.6.0, when certain LLVM versions are used, has compiler-induced secret-dependent control flow in lib/utils/ghash/ghash.cpp in GHASH in AES-GCM. There is a branch instead of an XOR with carry. This was observed for Clang in LLVM 15 on RISC-V. | |||
| CVE-2024-50383 | 0.00 | — | 0.01 | Oct 23, 2024 | Botan before 3.6.0, when certain GCC versions are used, has a compiler-induced secret-dependent operation in lib/utils/donna128.h in donna128 (used in Chacha-Poly1305 and x25519). An addition can be skipped if a carry is not set. This was observed for GCC 11.3.0 with -O2 on… | |||
| CVE-2024-39312 | 0.00 | — | 0.00 | Jul 8, 2024 | Botan is a C++ cryptography library. X.509 certificates can identify elliptic curves using either an object identifier or using explicit encoding of the parameters. A bug in the parsing of name constraint extensions in X.509 certificates meant that if the extension included both… | |||
| CVE-2017-7252 | 0.00 | — | 0.00 | Nov 3, 2023 | 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. | |||
| CVE-2021-24115 | 0.00 | — | 0.02 | Feb 22, 2021 | In Botan before 2.17.3, constant-time computations are not used for certain decoding and encoding operations (base32, base58, base64, and hex). | |||
| CVE-2018-20187 | 0.00 | — | 0.02 | Mar 8, 2019 | 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… | |||
