TITLE

Apple Quicktime UDTA ATOM Integer Overflow Vulnerability

DESCRIPTION

Integer overflow in Apple QuickTime before 7.1.5 allows remote user-assisted attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted QuickTime movie with a User Data Atom (UDTA) with an Atom size field with a large value. The Apple QuickTime player contains a heap buffer overflow vulnerability. This vulnerability may allow an attacker to execute arbitrary code or create a denial-of-service condition. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the parsing of forged size fields in user-defined data atoms (UDTA). By setting this field to an overly large value, an integer overflow occurs resulting in an exploitable heap overflow. Successful exploitation results in code execution under the context of the running user. Apple QuickTime is prone to multiple unspecified remote code-execution vulnerabilities including mulitple heap and stack-based buffer-overflow and integer-overflow issues. These issues arise when the application handles specially crafted 3GP, MIDI, MOV, PICT, and QTIF files. Successful attacks can result in the compromise of the applicaiton or can cause denial-of-service conditions. Few details regarding these issues are currently available. Separate BIDs for each issue will be created as new information becomes available. QuickTime versions prior to 7.1.5 are vulnerable.

Apple QuickTime udta ATOM Integer Overflow By Sowhat of Nevis Labs Date: 2007.03.06 http://www.nevisnetworks.com http://secway.org/advisory/AD20070306.txt http://secway.org/advisory/AD20060512.txt CVE: CVE-2007-0714 Vendor: Apple Inc. The CVE-2006-1460 does not patch the root cause of this vulnerability. The layout of a udta(user data atom) atom: Bytes _______________________ | User data atom | | Atom size | 4 | Type = 'udta' | 4 | | | User data list | | Atom size | 4 | Type = user data types| 4 | | ----------------------- By setting the value of the Atom size to a large value such as 0xFFFFFFFF, an insufficiently-sized heap block will be allocated, and resulting in a classic complete heap memory overwrite during the RtlAllocateHeap() function. Vendor Response: 2006.05.06 Vendor notified via product-security@apple.com 2006.05.07 Vendor responded 2006.05.09 Vendor ask for more information 2006.05.11 Vendor released QuickTime 7.1, the code path was influenced, but the root cause was not fixed. 2007.03.06 Vendor released the fixed version 2007.03.06 Advisory release Reference: 1. http://developer.apple.com/documentation/QuickTime/QTFF/index.html 2. http://docs.info.apple.com/article.html?artnum=305149 3. http://secway.org/advisory/AD20060512.txt -- Sowhat http://secway.org "Life is like a bug, Do you know how to exploit it ?"
