Synopsis

The remote Fedora host is missing a security update.

Description

#### 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.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected botan package.
