Background ========== CUPS provides a portable printing layer for UNIX-based operating systems. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-print/cups < 1.2.12-r7 >= 1.2.12-r7 Description =========== Multiple vulnerabilities have been reported in CUPS: * regenrecht (VeriSign iDefense) discovered that the cgiCompileSearch() function used in several CGI scripts in CUPS' administration interface does not correctly calculate boundaries when processing a user-provided regular expression, leading to a heap-based buffer overflow (CVE-2008-0047). * Helge Blischke reported a double free() vulnerability in the process_browse_data() function when adding or removing remote shared printers (CVE-2008-0882). * Tomas Hoger (Red Hat) reported that the gif_read_lzw() function uses the code_size value from GIF images without properly checking it, leading to a buffer overflow (CVE-2008-1373). * An unspecified input validation error was discovered in the HP-GL/2 filter (CVE-2008-0053). Impact ====== A local attacker could send specially crafted network packets or print jobs and possibly execute arbitrary code with the privileges of the user running CUPS (usually lp), or cause a Denial of Service. The vulnerabilities are exploitable via the network when CUPS is sharing printers remotely. 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-1.2.12-r7" References ========== [ 1 ] CVE-2008-0047 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-0047 [ 2 ] CVE-2008-0053 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-0053 [ 3 ] CVE-2008-0882 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-0882 [ 4 ] CVE-2008-1373 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1373 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200804-01.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.
