Background ========== FreeRADIUS is an open source RADIUS authentication server implementation. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-dialup/freeradius < 1.1.6 >= 1.1.6 Description =========== The Coverity Scan project has discovered a memory leak within the handling of certain malformed Diameter format values inside an EAP-TTLS tunnel. Impact ====== A remote attacker could send a large amount of specially crafted packets to a FreeRADIUS server using EAP-TTLS authentication and exhaust all memory, possibly resulting in a Denial of Service. Workaround ========== There is no known workaround at this time. Resolution ========== All FreeRADIUS users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-dialup/freeradius-1.1.6" References ========== [ 1 ] CVE-2007-2028 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-2028 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200704-14.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.
