* wildfly: Potential Memory leak in Wildfly when using OpenTracing (CVE-2020-27822)
* undertow: special character in query results in server errors (CVE-2020-27782)
* wildfly-core: memory leak in WildFly host-controller in domain mode while not able to reconnect to domain-controller (CVE-2020-25689)
* httpclient: apache-httpclient: incorrect handling of malformed authority component in request URIs (CVE-2020-13956)
* wildfly: resource adapter logs plaintext JMS password at warning level on connection error (CVE-2020-25640)
* resteasy-client: potential sensitive information leakage in JAX-RS RESTEasy Client's WebApplicationException handling (CVE-2020-25633)
For more details about the security issue(s), including the impact, a CVSS score, and other related information, see the CVE page(s) listed in the References section.

Apache HttpClient versions prior to version 4.5.13 and 5.0.3 can misinterpret malformed authority component in request URIs passed to the library as java.net.URI object and pick the wrong target host for request execution.
5.3 (Medium)
Vendor Fix
Before applying this update, back up your existing Red Hat JBoss Enterprise Application Platform installation and deployed applications.
The References section of this erratum contain a download link (you must log in to download the update).
The JBoss server process must be restarted for the update to take effect.
https://access.redhat.com/errata/RHSA-2021:0250
A flaw was found in the RESTEasy client in all versions of RESTEasy up to 4.5.6.Final. This flaw allows client users to obtain the server's potentially sensitive information when the server receives the WebApplicationException from the RESTEasy client call. The highest threat from this vulnerability is to confidentiality.
5.3 (Medium)
Vendor Fix
Before applying this update, back up your existing Red Hat JBoss Enterprise Application Platform installation and deployed applications.
The References section of this erratum contain a download link (you must log in to download the update).
The JBoss server process must be restarted for the update to take effect.
https://access.redhat.com/errata/RHSA-2021:0250
A flaw was found in wildfly. JMS passwords are logged by the resource adaptor in plain text at the warning level when a connection error occurs allowing any user that has access to the log to gain access to this sensitive information. The highest threat from this vulnerability is to data confidentiality.
5.3 (Medium)
Vendor Fix
Before applying this update, back up your existing Red Hat JBoss Enterprise Application Platform installation and deployed applications.
The References section of this erratum contain a download link (you must log in to download the update).
The JBoss server process must be restarted for the update to take effect.
https://access.redhat.com/errata/RHSA-2021:0250
A memory leak flaw was found in WildFly in all versions up to 21.0.0.Final, where the host-controller tries to reconnect in a loop, generating new connections that are not properly closed while unable to connect to the domain controller. This flaw allows an attacker to cause an Out of memory (OOM) issue, leading to a denial of service. The highest threat from this vulnerability is to system availability.
5.3 (Medium)
Vendor Fix
Before applying this update, back up your existing Red Hat JBoss Enterprise Application Platform installation and deployed applications.
The References section of this erratum contain a download link (you must log in to download the update).
The JBoss server process must be restarted for the update to take effect.
https://access.redhat.com/errata/RHSA-2021:0250
A flaw was found in the Undertow AJP connector. Malicious requests and abrupt connection closes could be triggered by an attacker using query strings with non-RFC compliant characters resulting in a denial of service. The highest threat from this vulnerability is to system availability.
7.5 (High)
Vendor Fix
Before applying this update, back up your existing Red Hat JBoss Enterprise Application Platform installation and deployed applications.
The References section of this erratum contain a download link (you must log in to download the update).
The JBoss server process must be restarted for the update to take effect.
https://access.redhat.com/errata/RHSA-2021:0250
Workaround
The issue can be mitigated by using HTTP/1.1 instead of AJP to proxy to the back-end.
A flaw was found in Wildfly. When an application uses the OpenTracing API's java-interceptors, there is a possibility of a memory leak. This flaw allows an attacker to impact the availability of the server. The highest threat from this vulnerability is to system availability.
5.9 (Medium)
Vendor Fix
Before applying this update, back up your existing Red Hat JBoss Enterprise Application Platform installation and deployed applications.
The References section of this erratum contain a download link (you must log in to download the update).
The JBoss server process must be restarted for the update to take effect.
