CVE-2021-41973

Name of the Vulnerable Software and Affected Versions Apache MINA versions prior to 2.1.5

Description A specifically crafted, malformed HTTP request may cause the HTTP Header decoder to loop indefinitely. The decoder assumed that the HTTP Header begins at the beginning of the buffer and loops if there is more data than expected.

Recommendations For Apache MINA versions prior to 2.1.5, update MINA to 2.1.5 or greater. As a temporary workaround, consider restricting the handling of HTTP requests to prevent indefinite looping until a patch is applied.
