There was a problem hiding this comment. After verifying the fix commit (apache/tomcat@8a83c3c), the only modified file is java/org/apache/tomcat/util/net/AprEndpoint.java. This file is not included in the org.apache.tomcat:tomcat-util artifact, so that package is not affected by this vulnerability. I've updated the affected packages list accordingly. |
