Updated rsync packages fix security vulnerabilities:

It was discovered that rsync incorrectly handled pointer arithmetic in zlib. An attacker could use this issue to cause rsync to crash, resulting in a denial of service, or possibly execute arbitrary code (CVE-2016-9840, CVE-2016-9841)

It was discovered that rsync incorrectly handled vectors involving left shifts of negative integers in zlib. An attacker could use this issue to cause rsync to crash, resulting in a denial of service, or possibly execute arbitrary code (CVE-2016-9842).

It was discovered that rsync incorrectly handled vectors involving big- endian CRC calculation in zlib. An attacker could use this issue to cause rsync to crash, resulting in a denial of service, or possibly execute arbitrary code (CVE-2016-9843).

Please note, we now compile against system zlib. If rsync fails to sync with older remote systems using compression (-z), you have either update the remote host to a newer version or disable compression.
