SCA: security update for org.apache.tomcat:tomcat (GHSA-44qp-qhfv-c7f6)

high Tenable Self-Hosted Container Security Plugin ID 409942

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A vulnerability in Apache Tomcat allows an attacker to remotely trigger a denial of service. An error
 introduced as part of a change to improve error handling during non-blocking I/O meant that the error flag
 associated with the Request object was not reset between requests. This meant that once a non-blocking I/O
 error occurred, all future requests handled by that request object would fail. Users were able to trigger
 non-blocking I/O errors, e.g. by dropping a connection, thereby creating the possibility of triggering a
 DoS. Applications that do not use non-blocking I/O are not exposed to this vulnerability. This issue
 affects Apache Tomcat 10.0.3 to 10.0.4; 9.0.44; 8.5.64. (CVE-2021-30639)
