Description
A localhost.localdomain whitelist entry in valid_host() in scheduler/client.c in CUPS before 2.2.2 allows remote attackers to execute arbitrary IPP commands by sending POST requests to the CUPS daemon in conjunction with DNS rebinding. The localhost.localdomain name is often resolved via a DNS server (neither the OS nor the web browser is responsible for ensuring that localhost.localdomain is 127.0.0.1).
Affected configurations
• apple cups (< 2.2.2)
• debian debian linux 7.0
• debian debian linux 8.0
• canonical ubuntu linux 14.04
• canonical ubuntu linux 16.04
