A 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 open a malicious image file. The specific flaw exists in the parsing of the pict file format. If an invalid length is specified for the UncompressedQuickTimeData opcode, a stack based buffer overflow occurs, allowing the execution of arbitrary code. QuickTime version 7.2 is affected.
