Background ========== CUPS provides a portable printing layer for UNIX-based operating systems. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-print/cups < 1.2.9 >= 1.2.9 Description =========== CUPS does not properly handle partially-negotiated SSL connections. Upon receiving a partially-negotiated SSL connection, CUPS no longer accepts further incoming connections, as the initial connection never times out. Impact ====== An attacker could partially negotiate an SSL connection with a CUPS server, and cause future connections to that server to fail, resulting in a Denial of Service. 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-1.2.9" References ========== [ 1 ] CVE-2007-0720 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0720 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200703-28.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.
