Apple QuickTime PICT Integer Overflow Vulnerability
<http://www.apple.com/quicktime/> Quicktime is Apple's "media player
product, and is used to render video and other media. The PICT file format
was developed by Apple Inc. in 1984. PICT files can contain both object
oriented images and bitmaps". Remote exploitation of an integer overflow
in Apple Inc.'s QuickTime could allow an attacker to execute arbitrary
code in the security context of the current user.
* Apple Inc.'s QuickTime version 7.4.5
* Apple Inc.'s QuickTime version 7.4
* Apple Inc.'s QuickTime version 7.5.5
QuickTime is vulnerable to an integer overflow vulnerability when handling
malformed PICT files. This issue results in heap corruption which can lead
to arbitrary code execution.
Exploitation of this issue results in arbitrary code execution in the
security context of the current user. An attacker would need to host a web
page containing a malformed PICT file. Upon visiting the malicious web
page exploitation would occur. Alternatively a malicious PICT file could
be attached to an e-mail.
iDefense recommends disabling the QuickTime Plug-in and altering the .pic
and .pict file type associations within the registry. Disabling the
plug-in will prevent web browsers from utilizing QuickTime Player to view
associated media files. Removing the file type associations within the
registry will prevent QuickTime Player and Picture Viewer from opening
pic and .pict files.
Apple has released QuickTime 7.5.5 which resolves this issue. More
information is available via Apple's QuickTime Security Update page at the
