CUPS Scheduler Discloses Information to Local Users
SecurityTracker Alert ID:  1020145
SecurityTracker URL:  http://securitytracker.com/id/1020145
CVE Reference:   CVE-2008-1033   (Links to External Site)
Date:  May 29 2008
Impact:   Disclosure of authentication information, Disclosure of system information, Disclosure of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   A vulnerability was reported in CUPS on Mac OS X. A local user can obtain potentially sensitive information.

The CUPS scheduler does not properly process authentication environment variables when printing with debug logging enabled. When a user prints to a password-protected printer with debug logging enabled, a local user may be able to obtain potentially sensitive information, such as the username, domain, and password.

Systems prior to Mac OS X v10.5 that have Security Update 2008-002 installed are not affected.

[Editor's note: It is not clear if systems other than Mac OS X are affected or not.]

Impact:   A local user can obtain potentially sensitive information.
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:
