Vulnerability Assessment Details

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

Vulnerability Assessment Summary
FreeRADIUS: SQL injection and Denial of Service vulnerability

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200505-13
(FreeRADIUS: SQL injection and Denial of Service vulnerability)


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 permiting 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.

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-dialup/freeradius-1.0.2-r4"
