USN-3451-1: OpenStack Swift vulnerabilities

11 October 2017

Several security issues were fixed in OpenStack Swift.



  • swift - OpenStack distributed virtual object store


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.
(CVE-2016-0737, CVE-2016-0738)
