The issue is related to a use-after-free error when handling the CMarkupPointer object, which can lead to remote code execution or denial of service. This occurs due to improper memory access, potentially allowing an attacker to execute arbitrary code in the context of the current user.

The issue is related to a use-after-free error when handling a TextBlockRun object, allowing an attacker to execute arbitrary code or cause a denial of service using a specially crafted website. This could corrupt memory, enabling the execution of arbitrary code in the context of the current user.

The issue is related to incorrect access to objects in memory, which can cause memory errors and allow an attacker to execute arbitrary code in the context of the current user. This is due to use-after-free vulnerabilities.

A remote code execution issue exists due to incorrect access to objects in memory, potentially causing memory corruption and allowing an attacker to execute arbitrary code in the context of the current user. This issue has been demonstrated by Sebastian Apelt and Andreas Schmidt during a Pwn2Own competition at CanSecWest 2014, showcasing the vulnerability's exploitability.
