1) An error in the handling of image description atoms can be exploited to cause a memory corruption when a user is enticed to open a specially crafted movie file.

2) A boundary error in the handling of Sample Table Sample Descriptor (STSD) atoms can be exploited to cause a heap-based buffer overflow when a user opens a specially crafted movie file.

3) Multiple errors exist in QuickTime for Java. These can be exploited by untrusted Java applets to disclose sensitive information or to execute arbitrary code with escalated privileges when a user visits a web page containing a malicious Java applet.

4) A boundary error exists in the processing of panorama sample atoms in QTVR (QuickTime Virtual Reality) movie files, which can be exploited to cause a heap-based buffer overflow when a user is enticed to open a specially crafted movie file.

5) A boundary error in the processing of PICT image files can be exploited to cause a stack-based buffer overflow when a user opens a specially crafted PICT image file containing an invalid length for the “UncompressedQuickTimeData” opcode.

6) Errors exist in the parsing of Poly type opcodes (opcodes 0×0070-74) and the PackBitsRgn field (Opcode 0×0099) when processing PICT image files. These can be exploited to cause a heap corruption when a user opens a specially crafted PICT image file.

7) An error in the parsing of CTAB atoms can be exploited to cause a heap-based buffer overflow when a user opens a specially crafted movie file containing an invalid color table.

Successful exploitation of these vulnerabilities allows execution of arbitrary code.

The vulnerabilities are reported in QuickTime prior to version 7.3.

Secunia has constructed the Online Software Inspector, which you can use to check if your local system is vulnerable. If you wish to scan your corporate network, then please refer to the Network Software Inspector.
