AI-suggested

Red Hat has released security updates addressing CVE-2024-5971 in Red Hat JBoss Enterprise Application Platform 8.0 and related Undertow components. Users should apply these official patches as per Red Hat's advisories (e.g., RHSA-2024:4392 and RHSA-2024:4884). Before applying updates, ensure all previous errata are applied. Patch status is confirmed as fixed in these advisories. No additional mitigation steps are indicated beyond applying the vendor-provided updates.

Description

A vulnerability was found in Undertow, where the chunked response hangs after the body was flushed. The response headers and body were sent but the client would continue waiting as Undertow does not send the expected 0\r\n termination of the chunked response. This results in uncontrolled resource consumption, leaving the server side to a denial of service attack. This happens only with Java 17 TLSv1.3 scenarios.
