Technical details
A vulnerability in Google Chrome prior to 55.0.2883.75 for Windows allowed a remote attacker to prevent downloaded files from receiving the 'Mark of the Web' (MotW) NTFS alternate data stream. By using a crafted HTML page, an attacker could trigger a download that bypasses this security zone identifier. This bypass is significant because Windows and other applications use the MotW to apply restrictive security policies, such as Protected View in Office or 'Open File - Security Warning' prompts. The vulnerability is categorized under CWE-19 (Data Processing Errors) and requires user interaction to visit a malicious site and initiate a download. The issue was resolved in version 55.0.2883.75.
