Tracker summary

CVE-2026-49017 unimportant priority: Debian including 1 source packages (swift), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.

Description:

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.
