Background ========== CUPS, the Common Unix Printing System, is a full-featured print server. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-print/cups < 1.3.10 >= 1.3.10 Description =========== The following issues were reported in CUPS: * iDefense reported an integer overflow in the _cupsImageReadTIFF() function in the "imagetops" filter, leading to a heap-based buffer overflow (CVE-2009-0163). * Aaron Siegel of Apple Product Security reported that the CUPS web interface does not verify the content of the "Host" HTTP header properly (CVE-2009-0164). * Braden Thomas and Drew Yao of Apple Product Security reported that CUPS is vulnerable to CVE-2009-0146, CVE-2009-0147 and CVE-2009-0166, found earlier in xpdf and poppler. Impact ====== A remote attacker might send or entice a user to send a specially crafted print job to CUPS, possibly resulting in the execution of arbitrary code with the privileges of the configured CUPS user -- by default this is "lp", or a Denial of Service. Furthermore, the web interface could be used to conduct DNS rebinding attacks. Workaround ========== There is no known workaround at this time. Resolution ========== All CUPS users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-print/cups-1.3.10" References ========== [ 1 ] CVE-2009-0146 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0146 [ 2 ] CVE-2009-0147 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0147 [ 3 ] CVE-2009-0163 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0163 [ 4 ] CVE-2009-0164 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0164 [ 5 ] CVE-2009-0166 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0166 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200904-20.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
