So far, no customers have reported any problems. If the vulnerability is exploited, it could cause Acrobat to
crash and run arbitrary code.
The fix, Update 2, works with Acrobat 4.05 and includes all bug fixes in Update 1. The machine must be operating on Acrobat 4.05. Before installing Update 2, previous versions must be upgraded.
The update does not address Macintosh and Unix versions of Acrobat, since the potential security hole isn't
found on those platforms.
Another word of caution: Hackers are distributing fraudulent Adobe security patches via e-mail. The company says the fix is only available at its Web site.
