TITLE:
Apple QuickTime Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA27523

VERIFY ADVISORY:
http://secunia.com/advisories/27523/

CRITICAL:
Highly critical

IMPACT:
Security Bypass, Exposure of sensitive information, 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 disclose sensitive information,
bypass certain security restrictions, and compromise a user's
system.

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
0x0070-74) and the PackBitsRgn field (Opcode 0x0099) 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.

SOLUTION:
Update to version 7.3.
