Title: FreeRADIUS: SQL injection and Denial of Service vulnerability (GLSA 200505-13)
Date: May 17, 2005
Updated: May 22, 2006
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.
FreeRADIUS is an open source RADIUS authentication server
Vulnerable: < 1.0.2-r4
Unaffected: >= 1.0.2-r4
Architectures: All supported architectures
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).
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
There are no known workarounds at this time.
All FreeRADIUS users should upgrade to the latest available version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-dialup/freeradius-1.0.2-r4"
