Background

Apache Tomcat is a Servlet-3.0/JSP-2.2 Container.

Description

Apache Tomcat improperly handles deserialization of files under specific circumstances.

Impact

A remote attacker could possibly execute arbitrary code with the privileges of the process, or cause a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All Apache Tomcat 7.x users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=www-servers/tomcat-7.0.104"

All Apache Tomcat 8.x users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=www-servers/tomcat-8.5.55"
