Vulnerability Details

CVEID: CVE-2019-9517 DESCRIPTION: Multiple vendors are vulnerable to a denial of service, caused by an Internal Data Buffering attack. By opening the HTTP/2 window so the peer can send without constraint and sending a stream of requests for a large response object, a remote attacker could consume excessive CPU resources.
CVSS Base Score: 7.5
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/165183&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID: CVE-2019-9518 DESCRIPTION: Multiple vendors are vulnerable to a denial of service, caused by a Empty Frame Flooding attack. By sending a stream of frames with an empty payload and without the end-of-stream flag, a remote attacker could consume excessive CPU resources.
CVSS Base Score: 7.5
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/164904&gt; for the current score

CVEID: CVE-2019-9511 DESCRIPTION: Multiple vendors are vulnerable to a denial of service, caused by a Data Dribble attack. By sending a HTTP/2 request by the HTTP/2 protocol stack (HTTP.sys) for an overly large amount of data from a specified resource over multiple streams, a remote attacker could consume excessive CPU resources.
