| Doc Text: |
A flaw was found in Apache HttpComponents Core. This vulnerability, located in the HTTP/2 HPACK decoder, allows a remote attacker to cause a denial of service. By sending oversized compressed header blocks, an attacker can exhaust memory resources before the system's configured header list size limit is applied. This can lead to the affected system becoming unresponsive.
