Title:	Apache Tomcat HTTP/2 Vulnerability (Oct 2020) - Linux
Summary:	Apache Tomcat is prone to an information disclosure vulnerability in HTTP/2.
Description:	Summary: Apache Tomcat is prone to an information disclosure vulnerability in HTTP/2. Vulnerability Insight: If an HTTP/2 client exceeded the agreed maximum number of concurrent streams for a connection (in violation of the HTTP/2 protocol), it is possible that a subsequent request made on that connection could contain HTTP headers - including HTTP/2 pseudo headers - from a previous request rather than the intended headers. This could lead to users seeing responses for unexpected resources. Affected Software/OS: Apache Tomcat 8.5.1 to 8.5.57, 9.0.0.M5 to 9.0.37 and 10.0.0-M1 to 10.0.0-M7. Solution: Update to version 8.5.58, 9.0.38, 10.0.0-M8 or later. CVSS Score: 4.0 CVSS Vector: AV:N/AC:L/Au:S/C:P/I:N/A:N
