CVE-2015-7825 [HIGH] CVE-2015-7825: botan before 1.11.22 improperly validates certificate paths, which allows remote attackers to cause 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-2016-9132 [CRITICAL] CWE-190 CVE-2016-9132: In Botan 1.8.0 through 1.11.33, when decoding BER data an integer overflow could occur, which would 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.

CVE-2016-8871 [MEDIUM] CWE-200 CVE-2016-8871: In Botan 1.11.29 through 1.11.32, RSA decryption with certain padding options had a detectable timin 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-2016-2195 [CRITICAL] CWE-119 CVE-2016-2195: Integer overflow in the PointGFp constructor in Botan before 1.10.11 and 1.11.x before 1.11.27 allow 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-2016-2196 [CRITICAL] CWE-119 CVE-2016-2196: Heap-based buffer overflow in the P-521 reduction function in Botan 1.11.x before 1.11.27 allows rem 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-2014-9742 [HIGH] CWE-310 CVE-2014-9742: The Miller-Rabin primality check in Botan before 1.10.8 and 1.11.x before 1.11.9 improperly uses a s 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.

CVE-2016-2850 [HIGH] CWE-20 CVE-2016-2850: Botan 1.11.x before 1.11.29 does not enforce TLS policy for (1) signature algorithms and (2) ECC cur 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-2015-5726 [HIGH] CWE-20 CVE-2015-5726: The BER decoder in Botan 0.10.x before 1.10.10 and 1.11.x before 1.11.19 allows remote attackers to 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-2016-2194 [HIGH] CWE-20 CVE-2016-2194: The ressol function in Botan before 1.10.11 and 1.11.x before 1.11.27 allows remote attackers to cau 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-2015-5727 [HIGH] CWE-399 CVE-2015-5727: The BER decoder in Botan 1.10.x before 1.10.10 and 1.11.x before 1.11.19 allows remote attackers to 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-2015-7827 [HIGH] CWE-200 CVE-2015-7827: Botan before 1.10.13 and 1.11.x before 1.11.22 make it easier for remote attackers to conduct millio 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-2016-2849 [HIGH] CWE-200 CVE-2016-2849: Botan before 1.10.13 and 1.11.x before 1.11.29 do not use a constant-time algorithm to perform a mod 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.
