TITLE:
Apple QuickTime Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA33632

VERIFY ADVISORY:
http://secunia.com/advisories/33632/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Apple QuickTime 7.x
http://secunia.com/advisories/product/5090/

DESCRIPTION:
Some vulnerabilities have been reported in Apple QuickTime, which can
be exploited by malicious people to compromise a user's system.

1) A boundary error exists in the processing of RTSP URLs. This can
be exploited to cause a heap-based buffer overflow when a specially
crafted RTSP URL is accessed.

2) An error due to improper validation of transform matrix data
exists when processing Track Header (THKD) atoms in QuickTime Virtual
Reality (QTVR) movie files. This can be exploited to cause a
heap-based buffer overflow via a specially crafted QTVR file.

3) An error in the processing of "nBlockAlign" values in the
"_WAVEFORMATEX" structure of AVI headers can be exploited to cause a
heap-based buffer overflow when a specially crafted AVI file is
accessed.

4) A boundary error exists in the processing of MPEG-2 video files
containing MP3  audio content, which can be exploited to cause a
buffer overflow via a specially crafted movie file.

5) An unspecified error exists in the processing of H.263 encoded
movie files, which can be exploited to cause a memory corruption when
a specially crafted movie file is viewed.

6) A signedness error exists within the processing of the MDAT atom
when handling Cinepak encoded movie files. This can be exploited to
cause a heap-based buffer overflow when a specially crafted movie
file is viewed.

7) An error exists within the function JPEG_DComponentDispatch() when
processing the image width data in JPEG atoms embedded in STSD atoms.
This can be exploited to cause a memory corruption when a specially
crafted movie file is viewed.

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

SOLUTION:
Update to version 7.6.
