What is CVE-2016-0738?

OpenStack Object Storage (Swift) versions prior to 2.3.1, all 2.4.x versions, and 2.5.x versions before 2.5.1 do not effectively manage server connections. This vulnerability allows remote attackers to execute a denial of service attack by sending a sequence of interrupted requests to a Large Object URL. As a result, the proxy server can exhaust its resources, making it unable to fulfill legitimate requests. Users are advised to upgrade to the latest versions to mitigate this risk.
