Hi,

the following vulnerability was published for botan1.10.

CVE-2017-14737[0]:
| A cryptographic cache-based side channel in the RSA implementation in
| Botan before 1.10.17, and 1.11.x and 2.x before 2.3.0, allows a local
| attacker to recover information about RSA secret keys, as demonstrated
| by CacheD. This occurs because an array is indexed with bits derived
| from a secret key.

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
