Background ========== CUPS provides a portable printing layer for UNIX-based operating systems. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-print/cups < 1.2.12-r8 >= 1.2.12-r8 Description =========== Thomas Pollet reported a possible integer overflow vulnerability in the PNG image handling in the file filter/image-png.c. Impact ====== A malicious user might be able to execute arbitrary code with the privileges of the user running CUPS (usually lp), or cause a Denial of Service by sending a specially crafted PNG image to the print server. The vulnerability is exploitable via the network if 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-r8" References ========== [ 1 ] CVE-2008-1722 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1722 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200804-23.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.
