CVE-2015-5727

CVE-2015-5727 affects Botan BER decoder. Multiple connected advisories (Debian DSA-3565, OpenVAS NASL) confirm the issue: the BER decoder could allocate a large amount of memory when processing a length field, enabling a denial of service through memory exhaustion. Affected: Botan 1.10.x before 1...

CVE-2016-2194

CVE-2016-2194 affects Botan: the ressol function (Tonelli–Shanks) can enter an infinite loop when given a composite modulus, exposed through ECC point decompression (OS2ECP). This enables a remote DoS condition. Several advisories (Debian DSA-3565, Gentoo GLSA-201612-38, Mageia MGASA-2016-0102, F...

CVE-2015-5726

The CVE-2015-5726 issue affects Botan BER decoder: an empty BIT STRING in ASN.1 data can cause a remote denial of service (application crash) in Botan 0.10.x before 1.10.10 and 1.11.x before 1.11.19. Debian advisories confirm fixes for botan1.10 in Jessie (upgrade to 1.10.8-2+deb8u1). If applicab...

CVE-2014-9742

CVE-2014-9742 : The Miller–Rabin primality test in Botan before 1.10.8 and in 1.11.x before 1.11.9 improperly uses a single random base, weakening cryptographic protection for Diffie–Hellman groups. Connected advisories confirm this vulnerability in Botan’s pre-1.10.8 and specific 1.11.x releases...

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 modular inverse on the signature nonce k, which might allow remote attackers to obtain ECDSA secret keys via a timing side-channel attack...

CVE-2016-2850

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-2016-2196

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-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 cause a denial of service memory consumption via unspecified vectors, related to a length field...

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 single random base, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via a DH group...

CVE-2016-2849

CVE-2016-2849 affects Botan: the library did not use a constant-time algorithm for modular inverse during ECDSA signing, enabling timing side-channel leakage that could reveal ECDSA secret keys. Affected are Botan versions before 1.10.13 and 1.11.x before 1.11.29. Impact is a remote attacker pote...

Fedora 24 : botan-1.10.13-1.fc24 (2016-a545f81683)

From the upstream release notes: Botan 1.10.13 has been released backporting some side channel protections for ECDSA signatures CVE-2016-2849 and PKCS 1 RSA decryption CVE-2015-7827. Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security...
