Severity: moderate Description:
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 This issue is being tracked as JAMES-3635 Mitigation: 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. Credit: Apache James PMC would like to thanks Benoit TELLIER for this report.
