Description

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) 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 recover the ECDSA secret key (CVE-2016-2849).
