NVD Description

Note: Versions mentioned in the description apply only to the upstream openstack-swift-account package and not the openstack-swift-account package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

In OpenStack Swift before 2.36.2 and 2.37.2, s3api middleware enters an infinite loop when processing a truncated aws-chunked PUT request body. The StreamingInput class repeatedly appends an empty buffer and re-reads, causing the proxy-server worker handling the request to become permanently unresponsive with increasing CPU and memory consumption. An authenticated attacker can systematically exhaust all proxy-server workers, resulting in denial of service. The defect was introduced in Swift 2.36.0.
