Описание
Allocation of resources without limits or throttling in the HTTP/2 HPACK decoder in Apache HttpComponents Core (5.4.2 and earlier, 5.5-beta1 and earlier) allows an remote attacker to cause a denial of service through memory exhaustion by sending oversized compressed header blocks before the HTTP/2 SETTINGS acknowledgement causes the configured header list size limit to be applied.
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.
Отчет
This is an Important denial of service vulnerability in Apache HttpComponents Core. The HTTP/2 HPACK decoder is susceptible to memory exhaustion when processing oversized compressed header blocks from a remote attacker. This occurs before the system's configured header list size limits are applied, potentially rendering affected Red Hat products unresponsive.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
