A vulnerability was found in GNU FreeRADIUS 1.0.3/1.0.4 (Network Authentication Software). It has been classified as critical. Affected is an unknown code block of the file xlat.c. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Off-by-one error in the sql_error function in sql_unixodbc.c in FreeRADIUS 1.0.2.5-5, and possibly other versions including 1.0.4, might allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by causing the external database query to fail. NOTE: this single issue is part of a larger-scale disclosure, originally by SUSE, which reported multiple issues that were disputed by FreeRADIUS. Disputed issues included file descriptor leaks, memory disclosure, LDAP injection, and other issues. Without additional information, the most recent FreeRADIUS report is being regarded as the authoritative source for this CVE identifier.

The weakness was shared 09/08/2005 with Red Hat as Bug 167676 as not defined bug report (Bugzilla). The advisory is available at bugzilla.redhat.com. This vulnerability is traded as CVE-2005-4744 since 03/28/2006. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication.
