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"
