CVE-2016-0737
OpenStack Object Storage (Swift) before 2.4.0 does not properly close client connections, which allows remote attackers to cause a denial of service (proxy-server resource consumption) via a series of interrupted requests to a Large Object URL.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.82%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
