Malicious content could allow Flash Player to conduct a HTTP response
splitting attack. (CVE-2007-6245)

A flaw was found in the way Flash Player processes certain SWF content. A
malicious SWF file could allow a remote attacker to conduct a port scanning
attack from the client's machine. (CVE-2007-4324)

attacker could use Flash Player to conduct a DNS rebinding attack.
