CVE-2023-28709

Denial of Service. If non-default HTTP connector settings were used such that the maxParameterCount could be reached using query string parameters and a request was submitted that supplied exactly maxParameterCount parameters in the query string, the limit for uploaded request parts could be bypassed with the potential for a denial of service to occur.

CVE-2023-41080

Open redirect. If the ROOT (default) web application is configured to use FORM authentication then it is possible that a specially crafted URL could be used to trigger a redirect to an URL of the attackers choice.

CVE-2023-42795

Information Disclosure. When recycling various internal objects, including the request and the response, prior to re-use by the next request/response, 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.

CVE-2023-44487

DoS caused by HTTP/2 frame overhead (Rapid Reset Attack)

CVE-2023-45648

Request smuggling. Tomcat 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.

For the stable distribution (bookworm), these problems have been fixed in version 10.1.6-1+deb12u1.

We recommend that you upgrade your tomcat10 packages.

For the detailed security status of tomcat10 please refer to its security tracker page at: [link moved to references]");
