Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Pound is vulnerable to a buffer overflow that could lead to the remote |
| 19 |
execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Pound is a reverse proxy, load balancer and HTTPS front-end. |
| 25 |
|
| 26 |
Affected packages |

Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Steven Van Acker has discovered a buffer overflow vulnerability in the |
| 38 |
"add_port()" function in Pound. |
| 39 |
|
| 40 |
Impact |
| 41 |
====== |
| 42 |
|
| 43 |
A remote attacker could send a request for an overly long hostname |
| 44 |
parameter, which could lead to the remote execution of arbitrary code |
| 45 |
with the rights of the Pound daemon process (by default, Gentoo uses |
| 46 |
the "nobody" user to run the Pound daemon). |
| 47 |
|
| 48 |
Workaround |
| 49 |
========== |
| 50 |
|
| 51 |
There is no known workaround at this time. |
| 52 |
|
| 53 |
Resolution |
| 54 |
========== |
| 55 |
|
| 56 |
All Pound users should upgrade to the latest version: |
| 57 |
|
| 58 |
# emerge --sync |
| 59 |
# emerge --ask --oneshot --verbose ">=www-servers/pound-1.8.3" |
| 60 |
