RHSA-2015:2523 - Important: rh-java-common-apache-commons-collections security update

Synopsis

Important: rh-java-common-apache-commons-collections security update

Type/Severity

Security Advisory Important

Topic

Updated rh-java-common-apache-commons-collections packages which fix one security issue are now available for Red Hat Software Collections 2.

Red Hat Product Security has rated this update as having Important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

Description

The Apache Commons Collections library provides new interfaces, implementations, and utilities to extend the features of the Java Collections Framework.

It was found that the Apache commons-collections library permitted code execution when deserializing objects involving a specially constructed chain of classes. A remote attacker could use this flaw to execute arbitrary code with the permissions of the application using the commons-collections library. (CVE-2015-7501)

With this update, deserialization of certain classes in the commons-collections library is no longer allowed. Applications that require those classes to be deserialized can use the system property "org.apache.commons.collections.enableUnsafeSerialization" to re-enable their deserialization.

All users of rh-java-common-apache-commons-collections are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. All running applications using the commons-collections library must be restarted for the update to take effect.

Before applying this update, make sure all previously released errata relevant to your system have been applied.
