commons-beanutils regression
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.04 LTS

Summary:

USN-8322-1 introduced a regression in Apache Commons BeanUtils

Software Description:
- commons-beanutils: Apache Commons BeanUtils - Utility for manipulating Java beans

Details:

USN-8322-1 fixed a vulnerability in Apache Commons BeanUtils. It was
discovered that for Ubuntu 18.04 LTS, during the update preparation
phase, a previous fix for CVE-2014-0114 and CVE-2019-10086 was
incorrectly dropped. This update reintroduces the fix for
CVE-2014-0114 and CVE-2019-10086.

We apologize for the inconvenience.

Original advisory details:

 It was discovered that Apache Commons BeanUtils incorrectly allowed
 access to the declaredClass property of Java enum objects when handling
 externally supplied property paths. An attacker could possibly use this
 issue to execute arbitrary code.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 16.04 LTS
  libcommons-beanutils-java       1.9.2-3ubuntu0.1~esm2
                                  Available with Ubuntu Pro

In general, a standard system update will make all the necessary changes.
