The Apple Security Team reports that there are multiple
vulnerabilities within QuickTime (one of the plugins for
win32-codecs). A remote attacker capable of creating a
malicious SGI image, FlashPix, FLC movie, or a QuickTime
movie can possibly lead to execution of arbitrary code or
cause a Denial of Service (application crash).
Users who have QuickTime (/win32-codecs) as a browser plugin
may be vulnerable to remote code execution by visiting a
website containing a malicious SGI image, FlashPix, FLC movie
or a QuickTime movie.
