    Package : tomcat9
    CVE ID : CVE-2023-44487
    Debian Bug : 1053820

    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.

    For the detailed security status of tomcat9 please refer to
    its security tracker page at: https://security-tracker.debian.org/tracker/tomcat9
