GLSA 200505-13: FreeRADIUS: SQL injection and Denial of Service vulnerability

http://security.gentoo.org/

Severity:	normal
Title:	FreeRADIUS: SQL injection and Denial of Service vulnerability
Date:	05/17/2005
Bugs:	#91736
ID:	200505-13

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.

Background

FreeRADIUS is an open source RADIUS authentication server implementation.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-dialup/freeradius	< 1.0.2-r4	>= 1.0.2-r4	All supported architectures

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.

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-r4"
