Zero Day Initiative Advisory 10-262 – This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Quicktime. 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 how the application parses directBitsRect records within a .pict file. When decompressing data within this structure, the application will allocate space for the target buffer using fields described within the file and then use a different length to decompress the total data from the file. This can lead to code execution under the context of the application.
Zero Day Initiative Advisory 10-261 – This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple QuickTime. 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 application’s implementation of a custom compression algorithm. The application will trust a field within a DirectBitsRect structure which is used for an allocation, and later attempt to decompress data into this buffer. Due to the value for the allocation being different from the length of the data being decompressed a buffer overflow will occur which can lead to code execution with the privileges of the application.
Zero Day Initiative Advisory 10-260 – This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Quicktime. User interaction is required to exploit this vulnerability in that a user must be coerced into visiting a malicious page or opening a malicious file. The specific flaw exists within Apple’s support for Panoramic Images and occurs due to the application trusting a particular field for calculation of an offset. Due to the field being treated as a signed integer, the calculated offset can result in a pointer outside the bounds of the expected buffer. Upon usage of this out-of-bounds pointer, the application will write proceed to write image data to the invalid location. Successful exploitation can lead to code execution under the context of the application.
Zero Day Initiative Advisory 10-259 – This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Quicktime. User interaction is required in that a user must be coerced into opening up a malicious document or visiting a malicious website. The specific flaw exists within the way the application parses a particular property out of a flashpix file. The application will explicitly trust a field in the property as a length for a loop over an array of data structures. If this field’s value is larger than the number of objects, the application will utilize objects outside of this array. Successful exploitation can lead to code execution under the context of the application.
iDefense Security Advisory 12.07.10 – Remote exploitation of a memory corruption vulnerability in Apple Inc.’s QuickTime media player could allow attackers to execute arbitrary code in the context of the targeted user. The vulnerability specifically exists in the way specially crafted PICT image files are handled by the QuickTime PictureViewer. When processing specially crafted PICT image files, Quicktime PictureViewer uses a set value from the file to control the length of a byte swap operation. The byte swap operation is used to convert big endian data to little endian data. QuickTime fails to validate the length value properly before using it. When a length value is larger than the actual buffer size supplied, it will corrupt heap memory beyond the allocated buffer, which could lead to an exploitable condition. QuickTime Player versions prior to 7.6.9 are vulnerable.
Secunia Security Advisory – Multiple vulnerabilities have been reported in Apple iOS, which can be exploited by malicious people to conduct cross-site scripting and spoofing attacks, disclose sensitive information, bypass certain security restrictions, or to compromise a user’s system.
