ELSA-2024-0125 advisory.

  - Improper Input Validation vulnerability in Apache Tomcat.Tomcat from 11.0.0-M1 through 11.0.0-M11, from
    10.1.0-M1 through 10.1.13, from 9.0.0-M1 through 9.0.81 and from 8.5.0 through 8.5.93 did not correctly
    parse HTTP trailer headers. A specially crafted, invalid trailer header could cause Tomcat to treat a
    single request as multiple requests leading to the possibility of request smuggling when behind a reverse
    proxy. Users are recommended to upgrade to version 11.0.0-M12 onwards, 10.1.14 onwards, 9.0.81 onwards or
    8.5.94 onwards, which fix the issue. (CVE-2023-45648)

  - URL Redirection to Untrusted Site ('Open Redirect') vulnerability in FORM authentication feature Apache
    Tomcat.This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.0-M10, from 10.1.0-M1 through
    10.0.12, from 9.0.0-M1 through 9.0.79 and from 8.5.0 through 8.5.92. The vulnerability is limited to the
    ROOT (default) web application. (CVE-2023-41080)

  - Incomplete Cleanup vulnerability in Apache Tomcat.When recycling various internal objects in Apache Tomcat
    from 11.0.0-M1 through 11.0.0-M11, from 10.1.0-M1 through 10.1.13, from 9.0.0-M1 through 9.0.80 and from
    8.5.0 through 8.5.93, an error could cause Tomcat to skip some parts of the recycling process leading to
    information leaking from the current request/response to the next. Users are recommended to upgrade to
    version 11.0.0-M12 onwards, 10.1.14 onwards, 9.0.81 onwards or 8.5.94 onwards, which fixes the issue.
    (CVE-2023-42795)

  - Incomplete Cleanup vulnerability in Apache Tomcat. The internal fork of Commons FileUpload packaged with
    Apache Tomcat 9.0.70 through 9.0.80 and 8.5.85 through 8.5.93 included an unreleased, in progress
    refactoring that exposed a potential denial of service on Windows if a web application opened a stream for
    an uploaded file but failed to close the stream. The file would never be deleted from disk creating the
    possibility of an eventual denial of service due to the disk being full. Users are recommended to upgrade
    to version 9.0.81 onwards or 8.5.94 onwards, which fixes the issue. (CVE-2023-42794)
