    Summary


    Several security issues were fixed in OpenStack Swift.

    Software description

    Details


    It was discovered that OpenStack Swift incorrectly handled tempurls. A
    remote authenticated user in possession of a tempurl key authorized for PUT
    could retrieve other objects in the same Swift account. (CVE-2015-5223)

    Romain Le Disez and Örjan Persson discovered that OpenStack Swift
    incorrectly closed client connections. A remote attacker could possibly use
    this issue to consume resources, resulting in a denial of service.
