Fixed In Version: httpd 2.4.59
Doc Type: If docs needed, set a value
Doc Text:
A vulnerability was found in how Apache httpd implements the HTTP/2 protocol. There are insufficient limitations placed on the amount of CONTINUATION frames that can be sent within a single stream. This issue could allow an unauthenticated remote attacker to send packets to vulnerable servers, which could use up memory resources to cause a Denial of Service.

Description Nick Tait 2024-03-06 21:33:06 UTC 
This description was provided in the disclosure from VINCE:

HTTP/2 CONTINUATION frames without the END_HEADERS flag set can be sent in a continuous stream by an attacker to an Apache Httpd implementation, which will not properly terminate the request early, causing an OOM crash.

[note: edited "which will not properly append header information in memory" to "which will not properly terminate the request early" per note from Apache in VINCE]
