Message-ID: <200505171627.27285.jaervosz@gentoo.org> Date: Sun Jul 17 14:25:53 2005 From: jaervosz at gentoo.org (Sune Kloppenborg Jeppesen) Subject: [gentoo-announce] [ GLSA 200505-13 ] FreeRADIUS: Buffer overflow and SQL injection vulnerability - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 200505-13 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - http://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: High Title: FreeRADIUS: Buffer overflow and SQL injection vulnerability Date: May 17, 2005 Bugs: #91736 ID: 200505-13 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== The FreeRADIUS server is vulnerable to a buffer overflow and an SQL injection attack, possibly allowing the compromise of the system. 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. Any security concerns should be addressed to security@...too.org or alternatively, you may file a bug at http://bugs.gentoo.org.
