CVE-2017-16548
9.8
CRITICAL · CVSS 3.1 · EPSS 5.8% (pctl 93)
In your normal cycle
Critical by CVSS (9.8), but no sign of active exploitation.
Description
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.
