Overview
Affected versions of this package are vulnerable to Out-of-bounds Write via the processing of XML policy files containing a large number of nested elements. An attacker can cause a system crash and potentially achieve arbitrary code execution by supplying a specially crafted XML policy file.
Note: This is only exploitable if the attacker has high privileged access to place malicious policy files in directories owned by the root user.
