CVE-2016-2849 (opens in a new tab)How to fix?
There is no fixed version for Ubuntu:16.04 botan1.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream botan1.10 package and not the botan1.10 package as distributed by Ubuntu.
See How to fix? for Ubuntu:16.04 relevant fixed versions and status.
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.
