NVD Description

Note: Versions mentioned in the description apply only to the upstream undertow package and not the undertow package as distributed by Debian. See How to fix? for Debian:14 relevant fixed versions and status.

A flaw was found in undertow. This issue makes achieving a denial of service possible due to an unexpected handshake status updated in SslConduit, where the loop never terminates.
