"#### Version 1.10.17, 2017-10-02 ####

  - Address a side channel affecting modular exponentiation.
    An attacker capable of a local or cross-VM cache
    analysis attack may be able to recover bits of secret
    exponents as used in RSA, DH, etc. (CVE-2017-14737)

  - Workaround a miscompilation bug in GCC 7 on x86-32
    affecting GOST-34.11 hash function. [GH
    #1192](https://github.com/randombit/botan/issues/1192)
    [GH
    #1148](https://github.com/randombit/botan/issues/1148)
    [GH #882](https://github.com/randombit/botan/issues/882)

  - Add SecureVector::data() function which returns the
    start of the buffer. This makes it slightly simpler to
    support both 1.10 and 2.x APIs in the same codebase.

  - When compiled by a C++11 (or later) compiler, a template
    typedef of SecureVector, secure_vector, is added. In 2.x
    this class is a std::vector with a custom allocator, so
    has a somewhat different interface than SecureVector in
    1.10. But this makes it slightly simpler to support both
    1.10 and 2.x APIs in the same codebase.

  - Fix a bug that prevented `configure.py` from running
    under Python3

  - Botan 1.10.x does not support the OpenSSL 1.1 API. Now
    the build will #error if OpenSSL 1.1 is detected. Avoid
    –with-openssl if compiling against 1.1 or later.
    [GH #753](https://github.com/randombit/botan/issues/753)

  - Import patches from Debian adding basic support for
    building on aarch64, ppc64le, or1k, and mipsn32
    platforms.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora update system website.
