EulerOS Virtualization 2.5.0 : cups (EulerOS-SA-2018-1329)
Medium Nessus Plugin ID 118417
SynopsisThe remote EulerOS Virtualization host is missing multiple security updates.
DescriptionAccording to the versions of the cups package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :
- CUPS printing system provides a portable printing layer for UNIX(r) operating systems. It has been developed by Apple Inc.to promote a standard printing solution for all UNIX vendors and users.CUPS provides the System V and Berkeley command-line interfaces.
- Security fix(es):
- 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-2017-18190)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
