Message-ID: <200505201435.20343.jaervosz@gentoo.org> Date: Sun Jul 17 14:17:08 2005 From: jaervosz at gentoo.org (Sune Kloppenborg Jeppesen) Subject: [gentoo-announce] ERRATA: [ GLSA 200505-13 ] FreeRADIUS: SQL injection and Denial of Service vulnerability - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory [ERRATA UPDATE] GLSA 200505-13:02 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - http://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: FreeRADIUS: SQL injection and Denial of Service vulnerability Date: May 17, 2005 Updated: May 20, 2005 Bugs: #91736 ID: 200505-13:02 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Errata ====== This advisory incorrectly described FreeRADIUS versions as being vulnerable to a remote compromise. After further verifications, it appears to only result in potential Denial of Service. The SQL injection issue is not affected by this. Many thanks to Nicolas Baradakis for bringing this to our attention. The corrected sections appear below. Synopsis ======== The FreeRADIUS server is vulnerable to an SQL injection attack and a buffer overflow, possibly resulting in disclosure and modification of data and Denial of Service. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-dialup/freeradius < 1.0.2-r4 >= 1.0.2-r4 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 an SQL injection or a buffer overflow, possibly leading to the disclosure and the modification of sensitive data or Denial of Service by crashing the server. Resolution ========== All FreeRADIUS users should upgrade to the latest available version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-dialup/freeradius-1.0.2-r4" 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.
