Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
A format string vulnerabilty has been found in GNU Radius, which could |
| 19 |
lead to the remote execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
GNU Radius is a GNU version of Radius, a server for remote user |
| 25 |
authentication and accounting. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |

|

------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 net-dialup/gnuradius < 1.4 >= 1.4 |
| 34 |
|
| 35 |
Description |
| 36 |
=========== |
| 37 |
|
| 38 |
A format string vulnerability was found in the sqllog function from the |
| 39 |
SQL accounting code for radiusd. That function is only used if one or |
| 40 |
more of the "postgresql", "mysql" or "odbc" USE flags are enabled, |
| 41 |
which is not the default, except for the "server" 2006.1 and 2007.0 |
| 42 |
profiles which enable the "mysql" USE flag. |
| 43 |
|
| 44 |
Impact |
| 45 |
====== |
| 46 |
|
| 47 |
An unauthenticated remote attacker could execute arbitrary code with |
| 48 |
the privileges of the user running radiusd, which may be the root user. |
| 49 |
It is important to note that there is no default GNU Radius user for |
| 50 |
Gentoo systems because no init script is provided with the package. |
| 51 |
|
| 52 |
Workaround |
| 53 |
========== |
| 54 |
|
| 55 |
There is no known workaround at this time. |
| 56 |
|
| 57 |
Resolution |
| 58 |
========== |
| 59 |
|
| 60 |
All GNU Radius users should upgrade to the latest version: |
| 61 |
|
| 62 |
# emerge --sync |
| 63 |
# emerge --ask --oneshot --verbose ">=net-dialup/gnuradius-1.4" |
| 64 |
|
