Red Hat has released an official security update in Red Hat JBoss Enterprise Application Platform version 8.1.3 that fixes this vulnerability by upgrading the Undertow component. Users should apply this update promptly. Before updating, ensure all previous errata are applied and back up existing installations and configurations. For detailed update instructions, refer to Red Hat's official guidance at https://access.redhat.com/articles/11258. No other mitigations are specified by the vendor.
Description
A flaw was found in Undertow that can cause remote denial of service attacks. When the server uses the FormEncodedDataDefinition.doParse(StreamSourceChannel) method to parse large form data encoding with application/x-www-form-urlencoded, the method will cause an OutOfMemory issue. This flaw allows unauthorized users to cause a remote denial of service (DoS) attack.
