Title:	CUPS < 2.0.3 Multiple Vulnerabilities - Active Check
Summary:	Common Unix Printing System (CUPS) is prone to multiple; vulnerabilities.
Description:	Summary: Common Unix Printing System (CUPS) is prone to multiple vulnerabilities. Vulnerability Insight: The following vulnerabilities exist: - CVE-2015-1158: An issue with how localized strings are handled in cupsd allows a reference counter to over-decrement when handling certain print job request errors. As a result, an attacker can prematurely free an arbitrary string of global scope, creating a dangling pointer to a repurposed block of memory on the heap. The dangling pointer causes ACL verification to fail when parsing 'admin/conf' and 'admin' ACLs. The ACL handling failure results in unrestricted access to privileged operations, allowing an unauthenticated remote user to upload a replacement CUPS configuration file and mount further attacks. - CVE-2015-1159: A cross-site scripting bug in the CUPS templating engine allows this bug to be exploited when a user browses the web. In certain cases, the CGI template can echo user input to file rather than escaping the text first. This may be used to set up a reflected XSS attack in the QUERY parameter of the web interface help page. By default, many linux distributions run with the web interface activated, OS X has the web interface deactivated by default. Vulnerability Impact: These vulnerabilities may allow a remote unauthenticated attacker access to privileged operations on the CUPS server and to execute arbitrary javascript in a user's browser. Affected Software/OS: CUPS prior to version 2.0.3 Solution: Update to version 2.0.3 or later. CVSS Score: 10.0 CVSS Vector: AV:N/AC:L/Au:N/C:C/I:C/A:C
