NVD Description
Note: Versions mentioned in the description apply only to the upstream tomcat-el-3_0-api
package and not the tomcat-el-3_0-api
package as distributed by SLES:15.0
.
See How to fix?
for SLES:15.0
relevant fixed versions and status.
If an HTTP/2 client connecting to Apache Tomcat 10.0.0-M1 to 10.0.0-M7, 9.0.0.M1 to 9.0.37 or 8.5.0 to 8.5.57 exceeded the agreed maximum number of concurrent streams for a connection (in violation of the HTTP/2 protocol), it was 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.
