CUPS 2.2.10 is a bug fix release that addresses issues in the scheduler, IPP Everywhere support, CUPS library, and USB printer support. Changes include:

• CVE-2018-4300: Linux session cookies used a predictable random number seed.
• The lpoptions command now works with IPP Everywhere printers that have not yet been added as local queues (Issue #5045)
• Added USB quirk rules (Issue #5395, Issue #5443)
• The generated PPD files for IPP Everywhere printers did not contain the cupsManualCopies keyword (Issue #5433)
• Kerberos credentials might be truncated (Issue #5435)
• The handling of MaxJobTime 0 did not match the documentation (Issue #5438)
• Incorporated the page accounting changes from CUPS 2.3 (Issue #5439)
• Fixed a bug adding a queue with the -E option (Issue #5440)
• Fixed a crash bug when mapping PPD duplex options to IPP attributes (rdar://46183976)

Enjoy!
