Some vulnerabilities have been reported in Apple QuickTime, which can be exploited by malicious people to disclose potentially sensitive information or compromise a vulnerable system.

1) An implementation error in QuickTime for Java allows untrusted Java applets to deserialize objects provided by QTJava. This can be exploited to disclose sensitive information or execute arbitrary code e.g. when a user visits a malicious web page.

2) An unspecified error in the handling of external URLs embedded in movie files can lead to information disclosure.

3) An input validation error in the handling of data reference atoms within movie files can be exploited to cause a buffer overflow when a specially crafted movie is viewed.

4) An unspecified error in the handling of movie media tracks can be exploited to cause a memory corruption when a specially crafted movie is viewed.

5) A boundary error exists in the quicktime.qts library when parsing "crgn" atoms. This can be exploited to cause a heap-based buffer overflow when a specially crafted movie file is viewed.

6) A boundary error in the parsing of Channel Compositor ("chan") atoms can be exploited to cause a heap-based buffer overflow when a specially crafted movie file is viewed.

7) A boundary error exists within quickTime.qts when parsing PICT files. This can be exploited to cause a heap-based buffer overflow when a specially crafted PICT image is viewed.

8) A boundary error exists within the quicktime.qts library when processing Kodak encoded images, which can be exploited to cause a heap-based buffer overflow.

NOTE: This vulnerability does not affect Mac OS X systems.

9) A boundary error in the handling of Animation codec content can be exploited to cause a heap-based buffer overflow when a specially crafted movie file is viewed.

NOTE: This vulnerability does not affect Mac OS X systems.

10) A boundary error exists in the parsing of "obji" atoms. This can be exploited to cause a stack-based buffer overflow via a specially crafted QuickTime VR movie file where the atom size is set to "0".

11) A boundary error in the parsing of the Clip opcode can be exploited to cause a heap-based buffer overflow when a specially crafted PICT image file is viewed.

Successful exploitation of these vulnerabilities may allow execution of arbitrary code.

Solution
Update to version 7.4.5.
