CVE-2018-5764
The parse_arguments function in options.c in rsyncd in rsync before 3.1.3 does not prevent multiple --protect-args uses, which allows remote attackers to bypass an argument-sanitization protection mechanism.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.39%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
