Vulnerability Details
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 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-2019-9517
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 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-2019-9515
DESCRIPTION: Multiple vendors are vulnerable to a denial of service, caused by a Settings Flood attack. By sending a stream of SETTINGS frames to the peer, a remote attacker could consume excessive CPU resources.

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-2019-9513
DESCRIPTION: Multiple vendors are vulnerable to a denial of service, caused by a Resource Loop attack. By creating multiple request streams and continually shuffling the priority of the streams, a remote attacker could consume excessive CPU resources.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/164639 for the current score

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2019-9512
DESCRIPTION: Multiple vendors are vulnerable to a denial of service, caused by a Ping Flood attack. By sending continual pings to an HTTP/2 peer, a remote attacker could consume excessive CPU resources.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/164903 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)
