Disclosure of authentication information, Disclosure of system information, Disclosure of user information|
Fix Available: Yes Vendor Confirmed: Yes |
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.]
A local user can obtain potentially sensitive information.|
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:|

Impact: Printing to password-protected printers with debug logging
enabled may lead to the disclosure of sensitive information
Description: An issue exists in the CUPS scheduler's check of the
authentication environment variables when debug logging is enabled.
This may lead to the disclosure of the username, domain, and password
when printing to a password-protected printer. This update addresses
the issue by properly validating environment variables. This issue
does not affect systems prior to Mac OS X v10.5 with Security Update
