TITLE

Apple Mac OS X of QuickTime Vulnerable to buffer overflow

DESCRIPTION

Buffer overflow in QuickTime in Apple Mac OS X 10.6.x before 10.6.5 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted MPEG movie file. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The flaw exists within the QuickTimeMPEG.qtx module. When handling an ELST atom's edit list table data large values are not handled properly. Specifically, the media rate field is explicitly trusted and can be abused to control memory copy operations. By specifying a large enough value, an attacker can utilize this to write to an arbitrary address in process memory. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the user. This issue affects Apple Mac OS X 10.6 to 10.6.4 and Mac OS X Server 10.6 to 10.6.4. NOTE: This issue was previously covered in BID 44778 (Apple Mac OS X Prior to 10.6.5 Multiple Security Vulnerabilities), but has been given its own record to better document it. Apple QuickTime is a very popular multimedia player. The flaw exists within the QuickTimeMPEG.qtx module. -- Vendor Response: Apple states: Fixed in Mac OS X 10.6.5: http://support.apple.com/kb/HT4435 -- Disclosure Timeline: 2010-07-20 - Vulnerability reported to vendor 2010-11-10 - Coordinated public release of advisory -- Credit: This vulnerability was discovered by: * Anonymous -- About the Zero Day Initiative (ZDI): Established by TippingPoint, The Zero Day Initiative (ZDI) represents a best-of-breed model for rewarding security researchers for responsibly disclosing discovered vulnerabilities.
