Packet Storm Security Advisories
Zero Day Initiative Advisory 12-135 - 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 way Apple QuickTime handles movies with the jpeg2k codec. When the size for a sample defined in the stsz atom is too big the QuickTime player fails to allocate the required memory for that sample. A pointer to the previous sample data still exists after the previous sample got freed. This pointer normally gets updated to point to the current sample data, but this does not happen when the allocation fails. The QuickTime player then re-uses the stale pointer and a use-after-free situation occurs. This can lead to remote code execution under that context of the current process.

Hack a Day
This portable sample player packs quite a punch. [Lee] wanted a nice portable way to take his samples with him, but refused to water-down the features just because it is portable. He set of goal of playing between 3-8 simultaneous notes from a large assortment of stored samples. Sample space was the first design consideration, [...]

Zero Day Initiative Advisory 11-344 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of RealNetworks RealPlayer. 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 way that the application allocates space for parsing sample data encoded with the RV20 codec. After allocation, the application will partially fill the allocation with sample data. Upon usage of this sample data, the application will use the uninitialized data to calculate an index that is then written into. This can lead to code execution under the context of the application.

Zero Day Initiative Advisory 11-337 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of RealNetworks Real Player. 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 sample data encoded with the RV30 codec. When parsing this sample data, the application will make an allocation and then fail to completely initialize the buffer. During decoding of the sample data, the application will explicitly trust an index from the partially filled buffer and then use that to calculate an address to write to. This can lead to memory corruption which can be converted into code execution under the context of the application.

Zero Day Initiative Advisory 11-333 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of RealNetworks RealPlayer. 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 ATRC codec parses sample data out of the media file. When reading bit sizes from the sample, the application will seek a structure that is used for consuming bits from the sample stream outside the bounds of the correct data. When decoding the sample, the application will use the transformed data to initialize another structure. Due to the sizes being unbound, this can be used to corrupt memory outside the original allocation. This type of memory corruption can be leveraged to gain code execution under the context of the application.

Zero Day Initiative Advisory 11-259 - 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 way QuickTime handles corrupt Sample Size atoms. When the value for 'Number of Entries' in this atom differs from the 'Number of Entries' in the Time-To-Sample atom, QuickTime will fill the Atom Sample Table with uninitialized data read from memory. This can later on result in a heap overflow when the data is used to calculate a loop counter to fill a heap buffer.

Zero Day Initiative Advisory 11-258 - 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 way Quicktime handles the Sample-to-Chunks table in media files with 'twos' audio codec. If a value for 'samples per chunk' is bigger than 8 times the sample rate from the 'Sample Description Atom' it will cause a buffer overflow during the parsing of the atom sample table. This can result in remote code execution under the context of the current user.
