Errata |
| 18 |
====== |
| 19 |
|
| 20 |
This advisory incorrectly described FreeRADIUS versions as being |
| 21 |
vulnerable to a remote compromise. After further verifications, it |
| 22 |
appears to only result in potential Denial of Service. The SQL injection |
| 23 |
issue is not affected by this. Many thanks to Nicolas Baradakis for |
| 24 |
bringing this to our attention. |
| 25 |
|
| 26 |
The corrected sections appear below. |
| 27 |
|
| 28 |
Synopsis |
| 29 |
======== |
| 30 |
|
| 31 |
The FreeRADIUS server is vulnerable to an SQL injection attack and a |
| 32 |
buffer overflow, possibly resulting in disclosure and modification of |
| 33 |
data and Denial of Service. |
| 34 |
|
| 35 |
Affected packages |
| 36 |
================= |
| 37 |
|
| 38 |
------------------------------------------------------------------- |
| 39 |
Package / Vulnerable / Unaffected |
| 40 |
------------------------------------------------------------------- |
| 41 |
1 net-dialup/freeradius < 1.0.2-r4 >= 1.0.2-r4 |
| 42 |
|
| 43 |
Description |
| 44 |
=========== |
| 45 |
|
| 46 |
Primoz Bratanic discovered that the sql_escape_func function of |
| 47 |
FreeRADIUS may be vulnerable to a buffer overflow (BID 13541). He also |
| 48 |
discovered that FreeRADIUS fails to sanitize user-input before using it |
| 49 |
in a SQL query, possibly allowing SQL command injection (BID 13540). |
| 50 |
|
| 51 |
Impact |
| 52 |
====== |
| 53 |
|
| 54 |
By supplying carefully crafted input, a malicious user could cause an |
| 55 |
SQL injection or a buffer overflow, possibly leading to the disclosure |
| 56 |
and the modification of sensitive data or Denial of Service by crashing |
| 57 |
the server. |
| 58 |
|
| 59 |
Resolution |
| 60 |
========== |
| 61 |
|
| 62 |
All FreeRADIUS users should upgrade to the latest available version: |
| 63 |
|
| 64 |
# emerge --sync |
| 65 |
# emerge --ask --oneshot --verbose ">=net-dialup/freeradius-1.0.2-r4" |
| 66 |
|
