Debian 8: DLA-1412-1 Critical: CUPS Remote Command Execution Summary

Two vulnerabilities affecting the cups printing server were found which can lead to arbitrary IPP command execution and denial of service. . Package : cups Version : 1.7.5-11+deb8u3 CVE ID : CVE-2017-18190 CVE-2017-18248 Two vulnerabilities affecting the cups printing server were found which can lead to arbitrary IPP command execution and denial of service. CVE-2017-18190 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). CVE-2017-18248 The add_job function in scheduler/ipp.c in CUPS before 2.2.6, when D-Bus support is enabled, can be crashed by remote attackers by sending print jobs with an invalid username, related to a D-Bus notification. For Debian 8 "Jessie", these problems have been fixed in version 1.7.5-11+deb8u3. We recommend that you upgrade your cups packages.
