漏洞描述
中文描述:

Apache Tomcat是美国阿帕奇（Apache）基金会的一款轻量级Web应用服务器。该程序实现了对Servlet和JavaServer Page（JSP）的支持。 Apache Tomcat 存在信息泄露漏洞，该漏洞源于可以重用HTTP 2连接上接收到的前一个流的HTTP请求头值，用于与后续流相关联的请求。虽然这很可能会导致错误和HTTP 2连接的关闭，但信息可能会在请求之间泄漏。以下产品及版本受到影响：10.0.0-M1 to 10.0.0-M9, 9.0.0-M1 to 9.0.39 and 8.5.0 to 8.5.59。

英文描述:

While investigating bug 64830 it was discovered that Apache Tomcat 10.0.0-M1 to 10.0.0-M9, 9.0.0-M1 to 9.0.39 and 8.5.0 to 8.5.59 could re-use an HTTP request header value from the previous stream received on an HTTP/2 connection for the request associated with the subsequent stream. While this would most likely lead to an error and the closure of the HTTP/2 connection, it is possible that information could leak between requests.
