TITLE:
Apple QuickTime Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA28502

VERIFY ADVISORY:
http://secunia.com/advisories/28502/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

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

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

1) An unspecified error exists in the handling of Sorenson 3 video
files, which can be exploited to cause a memory corruption and may
allow execution of arbitrary code.

2) An error exists in the processing of Macintosh Resources embedded
in QuickTime movies. This can be exploited to cause a memory
corruption via an overly large length value stored in the resource
header in a specially crafted QuickTime movie file.

3) An error in the parsing of malformed Image Descriptor (IDSC) atoms
can be exploited to cause a heap corruption via a specially crafted
movie file.

4) A boundary error exists within the processing of compressed PICT
images and can be exploited to cause a buffer overflow.

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

SOLUTION:
Update to QuickTime 7.4.
