CVE-2016-8871 1 Botan Project 1 Botan 2026-06-17 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.
CVE-2016-6879 1 Botan Project 1 Botan 2026-06-17 5.0 MEDIUM 7.5 HIGH
The X509_Certificate::allowed_usage function in botan 1.11.x before 1.11.31 might allow attackers to have unspecified impact by leveraging a call with more than one Key_Usage set in the enum value.
CVE-2016-6878 1 Botan Project 1 Botan 2026-06-17 7.5 HIGH 9.8 CRITICAL
The Curve25519 code in botan before 1.11.31, on systems without a native 128-bit integer type, might allow attackers to have unspecified impact via vectors related to undefined behavior, as demonstrated on 32-bit ARM systems compiled by Clang.
CVE-2016-2850 2 Botan Project, Fedoraproject 2 Botan, Fedora 2026-06-17 5.0 MEDIUM 7.5 HIGH
Botan 1.11.x before 1.11.29 does not enforce TLS policy for (1) signature algorithms and (2) ECC curves, which allows remote attackers to conduct downgrade attacks via unspecified vectors.
CVE-2016-2849 3 Botan Project, Debian, Fedoraproject 3 Botan, Debian Linux, Fedora 2026-06-17 5.0 MEDIUM 7.5 HIGH
Botan before 1.10.13 and 1.11.x before 1.11.29 do not use a constant-time algorithm to perform a modular inverse on the signature nonce k, which might allow remote attackers to obtain ECDSA secret keys via a timing side-channel attack.
CVE-2016-2196 1 Botan Project 1 Botan 2026-06-17 10.0 HIGH 9.8 CRITICAL
Heap-based buffer overflow in the P-521 reduction function in Botan 1.11.x before 1.11.27 allows remote attackers to cause a denial of service (memory overwrite and crash) or execute arbitrary code via unspecified vectors.
CVE-2016-2195 2 Botan Project, Debian 2 Botan, Debian Linux 2026-06-17 10.0 HIGH 9.8 CRITICAL
Integer overflow in the PointGFp constructor in Botan before 1.10.11 and 1.11.x before 1.11.27 allows remote attackers to overwrite memory and possibly execute arbitrary code via a crafted ECC point, which triggers a heap-based buffer overflow.
CVE-2016-2194 2 Botan Project, Debian 2 Botan, Debian Linux 2026-06-17 5.0 MEDIUM 7.5 HIGH
The ressol function in Botan before 1.10.11 and 1.11.x before 1.11.27 allows remote attackers to cause a denial of service (infinite loop) via unspecified input to the OS2ECP function, related to a composite modulus.
CVE-2015-7827 3 Botan Project, Debian, Fedoraproject 3 Botan, Debian Linux, Fedora 2026-06-17 5.0 MEDIUM 7.5 HIGH
Botan before 1.10.13 and 1.11.x before 1.11.22 make it easier for remote attackers to conduct million-message attacks by measuring time differences, related to decoding of PKCS#1 padding.
CVE-2015-7826 1 Botan Project 1 Botan 2026-06-17 7.5 HIGH 9.8 CRITICAL
botan 1.11.x before 1.11.22 improperly handles wildcard matching against hostnames, which might allow remote attackers to have unspecified impact via a valid X.509 certificate, as demonstrated by accepting *.example.com as a match for bar.foo.example.com.
CVE-2015-7825 1 Botan Project 1 Botan 2026-06-17 7.8 HIGH 7.5 HIGH
botan before 1.11.22 improperly validates certificate paths, which allows remote attackers to cause a denial of service (infinite loop and memory consumption) via a certificate with a loop in the certificate chain.
CVE-2015-7824 1 Botan Project 1 Botan 2026-06-17 5.0 MEDIUM 7.5 HIGH
botan 1.11.x before 1.11.22 makes it easier for remote attackers to decrypt TLS ciphertext data via a padding-oracle attack against TLS CBC ciphersuites.
CVE-2015-5727 2 Botan Project, Debian 2 Botan, Debian Linux 2026-06-17 7.8 HIGH 7.5 HIGH
The BER decoder in Botan 1.10.x before 1.10.10 and 1.11.x before 1.11.19 allows remote attackers to cause a denial of service (memory consumption) via unspecified vectors, related to a length field.
CVE-2015-5726 2 Botan Project, Debian 2 Botan, Debian Linux 2026-06-17 5.0 MEDIUM 7.5 HIGH
The BER decoder in Botan 0.10.x before 1.10.10 and 1.11.x before 1.11.19 allows remote attackers to cause a denial of service (application crash) via an empty BIT STRING in ASN.1 data.
CVE-2014-9742 1 Botan Project 1 Botan 2026-06-17 5.0 MEDIUM 7.5 HIGH
The Miller-Rabin primality check in Botan before 1.10.8 and 1.11.x before 1.11.9 improperly uses a single random base, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via a DH group.
