Security database references:

In Mitre's CVE dictionary: CVE-2023-24998, CVE-2023-41080, CVE-2023-42795, CVE-2023-44487, CVE-2023-45648.

More information:

The patch to address CVE-2023-44487 (Rapid Reset Attack) was incomplete and caused a regression when using asynchronous I/O (the default for NIO and NIO2). DATA frames must be included when calculating the HTTP/2 overhead count to ensure that connections are not prematurely terminated.

For the oldstable distribution (bullseye), this problem has been fixed in version 9.0.43-2~deb11u8.

We recommend that you upgrade your tomcat9 packages.
