An update for rubygem-puma is now available for openEuler-20.03-LTS-SP4 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2023-1983 Final 1.0 1.0 2023-12-29 Initial 2023-12-29 2023-12-29 openEuler SA Tool V1.0 2023-12-29 rubygem-puma security update An update for rubygem-puma is now available for openEuler-20.03-LTS-SP4. A simple, fast, threaded, and highly concurrent HTTP 1.1 server for Ruby/Rack applications. Security Fix(es): Puma is a HTTP 1.1 server for Ruby/Rack applications. Prior to versions 5.5.1 and 4.3.9, using `puma` with a proxy which forwards HTTP header values which contain the LF character could allow HTTP request smugggling. A client could smuggle a request through a proxy, causing the proxy to send a response back to another unknown client. The only proxy which has this behavior, as far as the Puma team is aware of, is Apache Traffic Server. If the proxy uses persistent connections and the client adds another request in via HTTP pipelining, the proxy may mistake it as the first request's body. Puma, however, would see it as two requests, and when processing the second request, send back a response that the proxy does not expect. If the proxy has reused the persistent connection to Puma to send another request for a different client, the second response from the first client will be sent to the second client. This vulnerability was patched in Puma 5.5.1 and 4.3.9. As a workaround, do not use Apache Traffic Server with `puma`.(CVE-2021-41136) An update for rubygem-puma is now available for openEuler-20.03-LTS-SP4. openEuler Security has rated this update as having a security impact of low.
