xtrabackup was updated to 2.1.8:

Disabled the "binary version check" functionality in the
VersionCheck module due to security concerns. The automatic
version check remains disabled in the openSUSE package.
[bnc#864194] CVE-2014-2029
More bugs fixed:
* do not discard read-ahead buffers through incorrect usage of
posic_fadvise() hints, which resulted in higher I/O rate on
the backup stage
* Spurious trailing data blocks that would normally be ignored
by InnoDB could lead to an assertion failure on the backup stage
* A spurious warning message could cause issues with third-party
wrapper scripts
* xbcrypt could fail with the xbcrypt:xb_crypt_read_chunk: unable
to read chunk iv size at offset error under some circumstances
* xbstream could sometimes hang when extracting a broken or
incomplete input stream
