Mac OS X Image Capture Lets Local Users View Files and Gain Elevated Privileges
SecurityTracker Alert ID:  1020141
SecurityTracker URL:  http://securitytracker.com/id/1020141
CVE Reference:   CVE-2008-1571, CVE-2008-1572   (Links to External Site)
Date:  May 29 2008
Impact:   Disclosure of system information, Disclosure of user information, User access via local system
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 10.4.11 and prior versions
Description:   Two vulnerabilities were reported in Mac OS X Image Capture. A local user can view files and obtain elevated privileges on the target system.

A local user can load a specially crafted URL to exploit a path traversal flaw in the Image Capture embedded web server and obtain files on the target system [CVE-2008-1571].

The system uses unsafe temporary files [CVE-2008-1572]. A local user can cause files to be overwritten by a target user with the privileges of the target user. A local user can also access the contents of images being resized by the target user.

Systems running Mac OS X v10.5 and later are not affected by either of these vulnerabilities.

Impact:   A remote user can view files on the target system.

A local user can obtain elevated privileges on the target system.

Solution:   The vendor has issued a fix as part of Security Update 2008-003 and Mac OS X v10.5.3, available from the Software Update pane in System Preferences, or Apple's Software Downloads web site at:
