Impact Analysis

This vulnerability can have serious impacts including the potential for an attacker to execute arbitrary code on your system.

Since the code execution happens with the current user's privileges, an attacker could perform actions such as installing programs, viewing, changing, or deleting data, or creating new accounts with full user rights.

However, exploitation requires that you open a malicious file, so practicing caution with files from untrusted sources can reduce risk.
