Description

XMLReader class can raise an exception if an invalid character is encountered, and the exception crosses stack frames in an unsafe way that causes a higher level exception handler to access an already-freed object.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
