Apache HTTP Server: HTTP/2 stream memory not reclaimed right away on RST
Vulnerability Description
When a HTTP/2 stream was reset (RST frame) by a client, there was a time window were the request's memory resources were not reclaimed immediately. Instead, de-allocation was deferred to connection close. A client could send new requests and resets, keeping the connection busy and open and causing the memory footprint to keep on growing. On connection close, all resources were reclaimed, but the process might run out of memory before that. This was found by the reporter during testing of CVE-2023-44487 (HTTP/2 Rapid Reset Exploit) with their own test client. During "normal" HTTP/2 use, the probability to hit this bug is very low. The kept memory would not become noticeable before the connection closes or times out. Users are recommended to upgrade to version 2.4.58, which fixes the issue.

Apache HTTP Server 资源管理错误漏洞
Vulnerability Description
Apache HTTP Server是美国阿帕奇（Apache）基金会的一款开源网页服务器。该服务器具有快速、可靠且可通过简单的API进行扩充的特点。 Apache HTTP Server mod_http2 存在资源管理错误漏洞，该漏洞源于当客户端重置 HTTP/2 流（RST 帧）时，存在一个时间窗口，请求的内存资源不会立即回收。相反，释放被推迟到连接关闭。客户端可以发送新请求并重置，使连接保持繁忙和打开状态，从而导致内存占用持续增长。连接关闭时，所有资源都会被回收，但进程可能会在连接关闭之前耗尽内存
