Version        : 9.0.31-1~deb10u8
CVE ID         : CVE-2022-42252 CVE-2023-28708
Debian Bug     : 1033475

Two security vulnerabilities have been discovered in the Tomcat
servlet and JSP engine.

CVE-2022-42252

    Apache Tomcat was configured to ignore invalid HTTP headers via setting
    rejectIllegalHeader to false. Tomcat did not reject a request containing an
    invalid Content-Length header making a request smuggling attack possible if
    Tomcat was located behind a reverse proxy that also failed to reject the
    request with the invalid header.

CVE-2023-28708

    When using the RemoteIpFilter with requests received from a reverse proxy
    via HTTP that include the X-Forwarded-Proto header set to https, session
    cookies created by Apache Tomcat did not include the secure attribute. This
    could result in the user agent transmitting the session cookie over an
    insecure channel.

For Debian 10 buster, these problems have been fixed in version
9.0.31-1~deb10u8.

We recommend that you upgrade your tomcat9 packages.
