Summary

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. Red Hat rates this as a Moderate impact since this requires the use of a specific form method by the server that must be externally available and the input is not sanitized by the given servlet or class implementing its use.

Weakness: CWE-20.

Affected products named by the advisory: Red Hat JBoss Enterprise Application Platform 7.1 EUS for RHEL 7; Red Hat JBoss Enterprise Application Platform 7.3 EUS for RHEL 7; Red Hat JBoss Enterprise Application Platform 7.4.24; Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 7; and 10 more.
