Updated botan packages fix security vulnerabilities

Updated botan packages fix security vulnerabilities: During RSA decryption, how long decoding of PKCS 1 v1.5 padding took was input dependent. If these differences could be measured by an attacker, it could be used to mount a Bleichenbacher million-message attack CVE-2015-7827. ECDSA and DSA...

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-2016-2849

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...

botan: multiple issues

CVE-2016-2849 ECDSA side channel: ECDSA and DSA signature algorithms perform a modular inverse on the signature nonce k. The modular inverse algorithm used had input dependent loops, and it is possible a side channel attack could recover sufficient information about the nonce to eventually...
