DATE CVE VULNERABILITY TITLE RISK
2017-04-10 CVE-2016-6879 Key Management Errors vulnerability in Botan Project Botan
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.

5.0
2017-04-10 CVE-2016-6878 Improper Input Validation vulnerability in Botan Project Botan
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.

7.5
2017-04-10 CVE-2015-7826 Improper Certificate Validation vulnerability in Botan Project Botan
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.

2017-04-10 CVE-2015-7825 Unspecified vulnerability in Botan Project Botan
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.

2017-04-10 CVE-2015-7824 Information Exposure vulnerability in Botan Project Botan
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.

5.0
2017-01-30 CVE-2016-9132 Integer Overflow or Wraparound vulnerability in Botan Project Botan
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.

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.

2.1
2016-05-13 CVE-2016-2850 Improper Input Validation vulnerability in multiple products
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.

5.0
2016-05-13 CVE-2016-2849 Information Exposure vulnerability in multiple products
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.

2016-05-13 CVE-2016-2196 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Botan Project Botan
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.
