In Apache James, using Jazzer fuzzer, we identified that an IMAP user can craft IMAP LIST commands to orchestrate a Denial Of Service using a vulnerable Regular expression. This affected Apache James prior to 3.6.1 We recommend upgrading to Apache James 3.6.1 or higher , which enforce the use of RE2J regular expression engine to execute regex in linear time without back-tracking. En Apache James, usando Jazzer fuzzer, identificamos que un usuario de IMAP puede diseñar comandos IMAP LIST para orquestar una denegación de servicio usando una expresión regular vulnerable. Esto afectaba a Apache James versiones anteriores a 3.6.1. Recomendamos actualizar a Apache James versión 3.6.1 o superior, que refuerza el uso del motor de expresiones regulares RE2J para ejecutar regex en tiempo lineal sin retroceso • http://www.openwall.com/lists/oss-security/2022/01/04/2 https://www.openwall.com/lists/oss-security/2022/01/04/2 •

Apache James prior to release 3.6.1 is vulnerable to a buffering attack relying on the use of the STARTTLS command. This can result in Man-in -the-middle command injection attacks, leading potentially to leakage of sensible information. Apache James versiones anteriores a 3.6.1, es vulnerable a un ataque de buffering que es basado en el uso del comando STARTTLS. Esto puede resultar en ataques de inyección de comandos de tipo "Man-in-the-middle", conllevando potencialmente a un filtrado de información confidencial • http://www.openwall.com/lists/oss-security/2022/01/04/1 http://www.openwall.com/lists/oss-security/2022/09/20/1 https://www.openwall.com/lists/oss-security/2022/01/04/1 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-327: Use of a Broken or Risky Cryptographic Algorithm •

Spooler in Apache Foundation James 2.2.0 allows local users to cause a denial of service (memory consumption) by triggering various error conditions in the retrieve function, which prevents a lock from being released and causes a memory leak. • http://issues.apache.org/jira/browse/JAMES-268 http://james.apache.org/changelog.html http://www.securityfocus.com/bid/15765 •
