Background ========== GNU Radius is a GNU version of Radius, a server for remote user authentication and accounting. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-dialup/gnuradius < 1.4 >= 1.4 Description =========== A format string vulnerability was found in the sqllog function from the SQL accounting code for radiusd. That function is only used if one or more of the "postgresql", "mysql" or "odbc" USE flags are enabled, which is not the default, except for the "server" 2006.1 and 2007.0 profiles which enable the "mysql" USE flag. Impact ====== An unauthenticated remote attacker could execute arbitrary code with the privileges of the user running radiusd, which may be the root user. It is important to note that there is no default GNU Radius user for Gentoo systems because no init script is provided with the package. Workaround ========== There is no known workaround at this time. Resolution ========== All GNU Radius users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-dialup/gnuradius-1.4" References ========== [ 1 ] CVE-2006-4181 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-4181 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200612-17.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.
