Description Ted Jongseok Won 2026-10-08 07:29:20 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

Initialization of a resource with an insecure default vulnerability in Apache Tomcat Native enabled insecure options by default  including ALLOW_CLIENT_RENEGOTIATION, NO_EXTENDED_MASTER_SECRET, IGNORE_UNEXPECTED_EOF and ALLOW_NO_DHE_KEX.



This issue affects Apache Tomcat Native: from 2.0.0 through 2.0.15, from 1.3.0 through 1.3.8. Earlier unsupported versions may also be affected.



Users are recommended to upgrade to version 2.0.16 or 1.3.9, which fix the issue.
