Description

This security bulletin contains information about 1 vulnerability.


1) Resource exhaustion (CVE-ID: N/A)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to improper resource management in the HTTP/2 transport server implementation when handling rapid client-initiated stream creation and reset sequences. A remote attacker can send a rapid flood of HEADERS followed by RST_STREAM frames to cause a denial of service.

The condition bypasses the HTTP/2 Rapid Reset mitigation because queued control buffer items do not count against the transport response frame threshold, leading to high CPU consumption.
