+title: 'Swift proxy-server DoS through Large Object'
+
+description: 'Romain LE DISEZ from OVH and Örjan Persson from Kiliaro independently
+    reported two vulnerabilities in Swift Large Object. By repeatedly
+    requesting and interrupting connections to a Large Object (Dynamic or
+    Static) URL, a remote attacker may exhausts Swift proxy-server
+    resources, potentially resulting in a denial of service. Note that there
+    are two distinct bugs that can exhaust proxy resources, one for client
+    connection (client to proxy), one for servers connection (proxy to
+    server). All Swift setup are affected.'
