Title
Apache HttpComponents Core: HPackDecoder Unlimited Header List Size Before SETTINGS ACK
Summary
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.
Severity ?
No CVSS data available.
