CVE-2015-5223

OpenStack Object Storage (Swift) before 2.4.0 allows attackers to obtain sensitive information via a PUT tempurl and a DLO object manifest that references an object in another container.

OpenStack Object Storage (Swift) before 2.4.0 allows attackers to obtain sensitive information via a PUT tempurl and a DLO object manifest that references an object in another container.

openstack-swift was updated to fix three security issues.

These security issues were fixed:

• CVE-2015-1856: OpenStack Object Storage (Swift), when allow_version is configured, allowed remote authenticated users to delete the latest version of an object by leveraging listing access to the x-versions-location container (bsc#927793).
• CVE-2014-7960: OpenStack Object Storage (Swift) allowed remote authenticated users to bypass the max_meta_count and other metadata constraints via multiple crafted requests which exceed the limit when combined (bsc#900253).
• CVE-2015-5223: Information leak via Swift tempurls (bsc#942641).

OpenStack Object Storage (Swift) before 2.4.0 allows attackers to obtain sensitive information via a PUT tempurl and a DLO object manifest that references an object in another container.

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)
