Background ========== FreeRADIUS is an open source RADIUS authentication server implementation. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-dialup/freeradius < 1.0.2-r3 >= 1.0.2-r3 Description =========== Primoz Bratanic discovered that the sql_escape_func function of FreeRADIUS may be vulnerable to a buffer overflow (BID 13541). He also discovered that FreeRADIUS fails to sanitize user-input before using it in a SQL query, possibly allowing SQL command injection (BID 13540). Impact ====== By supplying carefully crafted input, a malicious user could cause a buffer overflow or an SQL injection, possibly leading to the execution of arbitrary code or disclosure and the modification of sensitive data. Workaround ========== There are no known workarounds at this time. Resolution ========== All FreeRADIUS users should upgrade to the latest available version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-dialup/freeradius-1.0.2-r3" References ========== [ 1 ] BugTraq ID 13540 http://www.securityfocus.com/bid/13540/ [ 2 ] BugTraq ID 13541 http://www.securityfocus.com/bid/13541/ Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200505-13.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.
