TITLE

Apple Mac OS X of QuickTime Vulnerable to arbitrary code execution

DESCRIPTION

QuickTime in Apple Mac OS X 10.6.x before 10.6.5 accesses uninitialized memory locations during processing of GIF image data, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted GIF file. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple QuickTime. User interaction is required in that a target must open a malicious media file or visit a malicious page.The specific flaw exists within the application's implementation of the LZW compression when opening a certain file format. The application will allocate a buffer for the image and then decompress image data into it. Due to explicitly trusting the decompressed data, a buffer overflow will occur. This can lead to memory corruption and code execution under the context of the application. Successful exploits may allow attackers to execute arbitrary code in the context of the currently logged-in user; failed exploit attempts will cause denial-of-service conditions. 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. -- Vendor Response: Apple states: Fixed in Mac OS X 10.6.5: http://support.apple.com/kb/HT4435 -- Disclosure Timeline: 2010-06-30 - 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.
