How to Compromise the Enterprise Endpoint

Summary: Google Project Zero's Tavis Ormandy published details of multiple critical vulnerabilities in Symantec and Norton antivirus products, including wormable remote code execution flaws that need no user interaction, affect default configurations, and on Windows can corrupt kernel memory. Because Symantec uses the same core engine across its product line, all Symantec and Norton branded antivirus products are affected, and some cannot be automatically updated.
Bottom line: Ormandy's ASPack test case triggers on Windows through a filter driver that intercepts all system I/O, so simply emailing a file to a victim or sending a link is enough to compromise an entire enterprise fleet without the victim opening anything.
