CVE-2017-16548  (opens in a new tab)
CWE-119  (opens in a new tab)

How to fix?

Upgrade rsync to version 3.1.3-pre1 or higher.

Overview

Affected versions of this package are vulnerable to Out-of-Bounds. The receive_xattr function in xattrs.c in rsync 3.1.2 and 3.1.3-development does not check for a trailing '\0' character in an xattr name, which allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact by sending crafted data to the daemon.
