Apple has released updates for four security holes in QuickTime and fixed three flaws in the iPhone and iPod Touch. All four of the QuickTime vulnerabilities were able to end in “arbitrary code execution,” meaning that attacker can inject malware or hijack the system. None of the patches fix the vulnerability disclosed last week by Italian researcher Luigi Auriemma, who posted a proof-of-conceptexploit for another flaw in the Real-Time Streaming Protocol (RTSP).
