CVE-2017-16548Date: (C)2017-11-07   (M)2023-12-22


The receive_xattr function in xattrs.c in rsync 3.1.2 and 3.1.3-development does not check for a trailing '' 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.
