CUPS 1.7.4 fixes several networking and build issues, and addresses a symlink security issue in the web interface. Changes include:

• Security: The web interface incorrectly served symlinked files and files that were not world-readable, potentially leading to a disclosure of information (Issue #4450)
• The CUPS headers incorrectly needed libdispatch for blocks support (Issue #4397)
• CUPS did not compile when Avahi or mDNSResponder was not present (Issue #4402, Issue #4424)
• The “snmp” option did not work with the network backends (Issue #4422)
• The User directive in client.conf did not override the USER environment variable (Issue #4426)
• The web interface now properly shows a “Go” button for all text-based browsers (Issue #4425)
• The MaxJobTime directive now properly supports time values (Issue #4434)
• The RPM spec file did not work due to the new Brazilian Portuguese localization (Issue #4436)
• Fixed an “IPP read error” issue (Issue #4440)
• Fixed the –disable-libusb configure option (Issue #4439)
• Fixed the debug output from the DNS-SD backend when using Avahi (Issue #4444)
• Fixed a bug in the CUPS_SC_GET_DEVICE_ID handling by the network backends (Issue #4447)
• Added USB quirk rule for Lexmark E230 (Issue #4448)
• The LPD backend did not work with some versions of glibc (Issue #4452)

Enjoy!
