Description
An issue exists where
XML TOK DATA CHARS is not considered in the doCdataSection() function. This leads to a lack of handler call depth tracking for various calls from within handlers during policy violations, which can result in a use-after-free condition. A use-after-free is a memory corruption flaw that occurs when an application continues to use a pointer after it has been freed.Recommendations
Update to version 2.8.2.
